Smart Playlists

[deluan]

Smart playlists can be created as a json object into a file with .nsp extension and Navidrome will create a dynamic/query based playlist and keep it updated. These .nsp files will be imported the same way as normal playlists, i.e. at scan time. See comment below for a complete list of fields and operators available.

Some examples:

• Recently Played:

{
  "name": "Recently Played",
  "comment": "Recently played tracks",
  "all": [
    {"inTheLast": {"lastPlayed": 30}}
  ],
  "sort": "lastPlayed",
  "order": "desc",
  "limit": 100
}

• 80's Top Songs

{
  "all": [
    { "any": [
      {"is": {"loved": true}},
      {"gt": {"rating": 3}}
    ]},
    {"inTheRange": {"year": [1981, 1990]}}
  ],
  "sort": "year",
  "order": "desc",
  "limit": 25
}

• Favourites

{
  "all": [
    {"is": {"loved": true}}
  ],
  "sort": "dateLoved",
  "order": "desc",
  "limit": 500
}

• All songs in random order (not recommended for large libraries)

{
  "all": [
    {"gt": {"playCount":-1}}
  ],
  "sort": "random"
}

Hello, not sure if I should post this here or make a new issue.
I have a use case which is to find all the songs which are unrated. I want to find those which have no star.

I played a bit with the NSP, and my take is that it's like an expression tree which builds SQL queries. Haven't looked at the source, yet. And indeed, the "problem" is that
select * from annotation where rating = 0 and item_type = 'media_file'
returns only the songs with no rating, but they still need to have a row in the annotation table.

In effect I have only 10 songs returned without star. When in actuality I have thousands, but these have never been annotated.
So they are never in the scope of the expression tree. So they can never be found? Or is there another way?

EDIT: I wonder if there's like some sort of left outer join or something that would still target media_files which have no annotations yet, kinda like changing that LeftJoin in persistence/playlist_repository.go:207

Hello, not sure if I should post this here or make a new issue.

That's fine

I played a bit with the NSP, and my take is that it's like an expression tree which builds SQL queries. Haven't looked at the source, yet. And indeed, the "problem" is that select * from annotation where rating = 0 and item_type = 'media_file' returns only the songs with no rating, but they still need to have a row in the annotation table.

Yes, that's how it works, and yes, this is a "problem". I think a good approach for this is to introduce a new operator, isSet (true/false) that will be converted to is null/is not null and will allow these use cases where you don't have the record in the annotation table.

EDIT: I wonder if there's like some sort of left outer join or something that would still target media_files which have no annotations yet, kinda like changing that LeftJoin in persistence/playlist_repository.go:207

It is already a left join, the issue is that when there's no matching row in the annotation table, its values are all null

[deluan]

I actually did some experimentation and I think a better way is to wrap all fields from the left joined tables with COALESCE, like this:

COALESCE(annotation.rating, 0 ) = 0)

This will allow to use "is": {"rating": 0} in the NSP file.

First off, thanks for the smart playlists.. It really opens up the possibilities for Navidrome!

using the latest docker image (Navidrome Version: | 0.47.0 (8c7d95c)), trying to use dateadded and datemodified return invalid key errors. I'm attempting to make a Songs newly added and unrated playlist.. I took a cue from the random sorting post on reddit. Not sure if it would work, but it appears I can't filter on dateadded or datemodified. I'm assuming I'm doing something wrong, but just in case....

{
"all": [
{"is": {"rating": 0}},
{"datemodified": {"gt": "DATE('now','-90 day')"}}, -- using this line or the next..
{"dateadded": {"gt": "DATE('now','-90 day')"}}
],
"sort": "dateadded",
"order": "asc",
"limit": 100
}

time="2021-11-20T00:56:54Z" level=error msg="Error parsing SmartPlaylist" error="invalid expression key dateadded" playlist="Songs to Rate - Newly Added" requestId=e31872cd1409/MIUyT3LsdO-001067,

[deluan]

Hey @0bmay, the issue is that the key of the rule has to be the operator, not the field. So in the snippet:

{"dateadded": {"gt": "DATE('now','-90 day')"}}

should be:

{"gt": {"dateadded": "DATE('now','-90 day')"}}

Also notice the operator inTheLast, that was created specifically for this type of rules:

{"inTheLast": {"dateadded": "90"}}, 

I don't even know if DATE('now','-90 day') will work..

[0bmay]

Thank you @deluan!

Smart playlists are similar, but not the same as normal playlists in the Subsonic API - yet they are exposed via the same API endpoints. Some differences are, smart playlists are readonly, and are auto regenerated on read (I believe).
This poses some challenges for client apps / API consumers.

For client apps to be able to give a good user experience, information about what playlists are smart (readonly, auto regenerated) and what playlists are user edited is necessary. This information does not seem to be present with the current implementation.

Some points from a discord discussion on smart playlists in the context of the Subsonic API:

Is there any way of distinguishing smart playlists from plain old user-maintained playlists?

• so an app does not offer to add tracks to a smart playlist.
• so an app can know whether it syncs a changed user maintained playlist OR is refreshing a smart playlist.
• ...

Suggestion for one way to add extra information to the Subsonic API:

I think it's pretty safe to add properties to the existing Subsonic JSON/XML response outputs.
So one way could be to add a "navidrome:properties" object to the playlists:
"playlist": [
{
"navidrome:properties": {
"type": "smart", // smart, manual
....
}
"id": "af1a19a2-bafe-4b17-841c-73b0175891a3",
"name": "ABC",
"songCount": 0,
"duration": 0,
"public": false,
"owner": "demo",
"created": "2021-11-28T07:21:40.384665077Z",
"changed": "2021-12-03T09:13:46.098202015Z"
},

...

The presence of the "navidrome:properties" could also be conditional on the client sending some magic parameter in the request.

So in sum, one way to deliver extra playlist information to client apps would be:

• Add an extra, custom parameter to the getPlaylists.view request, for example: extensions=yes. When the server sees extensions=yes, it will output additional, non-standard, properties in the response.
• API consumers will have given the extensions=yes parameter, and be prepared to handle custom properties like "navidrome:properties".
• Legacy client apps will not give this parameter, and will therefore never see anything new.

Would it be possible to add playlist name/id as a selector field for the smart playlists? That way you can mix playlists together without all the hassle that it is now.

[AndersMoberg]

I renamed my NSP files to include emoji, and Navidrome started counting them as separate playlists.. ergo, it wouldn't purge the smart playlists that didn't have a file still.

Green are the new files, yellow are the previous names of these playlists.

[certuna]

Yes, playlist import is a one-direction process unfortunately. Change the name of the m3u/nsp, and it gets re-imported as a new playlist.

[ryoku-cha]

Is there any way to assign the Smart Playlists to any user (or all users)?

I tried putting the following in the .nsp File. But that did not change anything.
"owner": "username"
-> where username was the username for my account.

Currently my Smart Playlists appear only for the "admin" User, but not for my daily use user-account.

[TheWrathKing]

Is there any way to assign the Smart Playlists to any user (or all users)?

Yes, this is possible in the UI. When logged in as admin, click on the icon next to the word "Playlists" on the left side menu and in this new screen you can make the playlists 'public' or edit them.
In the 'Edit' screen you can change the owner of the playlist.
Hope this will help

[deluan]

Would it be possible to add playlist name/id as a selector field for the smart playlists? That way you can mix playlists together without all the hassle that it is now.

@aewne Yes, this is planned.

@MichaelBechHansen, I think a generic property instead of navidrome:properties would be a better approach, that could be used by other server implementations

[RedKage]

Hello, just a heads up while testing v0.47.5, it seems some of my smart playlists NSP are broken.
After a full refresh my playlists got emptied.
They contain NSP like this one

{
  "all": [
    {"is": {"rating": "5"}}
  ],
  "sort": "playcount",
  "order": "desc"
}

Which was working fine on the previous version.

The issue is that the value, in the above 5 is a string with double quotes in my NSP.
I changed my NSP with "rating": 5 without double quotes, touched and refresh and now they all work properly.

It makes sense, the value is a number.

This works as of 0.47.5

{
  "all": [
    {"is": {"rating": 5}}
  ],
  "sort": "playcount",
  "order": "desc"
}

This is not a bug, just an observation.

Also confirmed "rating": 0 works!
Thanks for the new release!

[gardebreak]

I have a "Recently Played" smart playlist:

{
  "all": [
    {"inTheLast": {"lastPlayed": 30}}
  ],
  "sort": "lastPlayed",
  "order": "desc",
  "limit": 50
}

Only tracks that I play through the web UI will show up on the list. It seems any tracks played on an external client don't get marked as "played." Is that the expected behavior?

[deluan]

@RedKage thanks for reporting this. I'll check if I can keep supporting both syntaxes in future releases

@gardebreak, you need to enable "Scrobbling" in your Subsonic client, see #593

[0bmay]

I think the smart play list sorting by random may be broken.. I'm getting back items that are sorted by song title instead..

{
"all": [
{ "any": [
{"is": {"loved": true}},
{"gt": {"rating": 3}}
]},
{"notInTheLast": {"lastPlayed": 180}},
{"contains": {"genre": "metal"}},
],
"sort": "random()",
"limit": 25,
"source": "https://www.reddit.com/r/navidrome/comments/qxh3qu/comment/hl9fb6x/?utm_source=reddit&utm_medium=web2x&context=3"
}

this returns a list of:

#EXTINF:260,Corporate Avenger - $20 Bill

songs that match the criteria, that all start with symbols or numbers, sorted by title. I would expect the listing to be more random. I know there were some changes to the smart lists in the latest release. Did random get broken, or is there a new way to randomize the returned data?

Thank you for all the hard work on navidrome.

[deluan]

Yeah, the fix to avoid possible SQL injections also closed this loophole. I just pushed a fix for random. Now you have to specify "sort": "random" (without ()) and it should work. To test it out and use it, please update to the latest dev build

[0bmay]

Thanks! I run navidrome from a docker image, so I will have to wait for either a dev build or a the next release. I didn't see anything in the documentation on how to build a docker image.

How can I exclude Compilations from a smart playlist?
I've made a few decade smart playlists like this one

{
  "all": [
    { "any": [
      {"is": {"loved": true}},
      {"gt": {"rating": 4}}
    ]},
    {"inTheRange": {"year": [2011, 2020]}},
  ],
  "sort": "random",
  "order": "desc",
  "limit": 500
}

but Compliations contain songs that have no relation to the compilation release date, so I see songs from the 80s/90s/00s even if the decade is 10s.
I have set all my albums with mp3Tag in the Grouping tag as Album/EP/Single/Live/Compilation/etc
In MusicBee I have cloned the same tag in the Disctype tag that is not visible in mp3Tag.
I see in the list at the beginning of this thread that there is a "compilation" entry that can be used in the smart playlists, but how do I use it? Does it refer to the same tags I've mentioned?
Because when I tried to add
{"compilation": false}
after
{"gt": {"rating": 4}}
Navidrome completely ignored the smart playlist.

[metalheim]

How can I exclude Compilations from a smart playlist?

It works on the "compilation" tag (TCMP in id3 tags).
You can see this if an album has it set by clicking on the "three dot menu" -> more information.

Try adding the compilation tag and then add someting like this to your smartplaylist:

{"is": {"compilation": false}},

[janaxhell]

Ok about the smartpalylist entry.
About TCMP in id3 tags: is this what in mp3Tag is Value->Extended Fields->Compilation and can be added to visible columns as %compilation%?
So I should retag all my compilations in that field with "1"?
EDIT
Seems like so: after adding that tag to visible columns, when I set it to "1", in MusicBee I see the tag "iTunes Compilation" changing from No to Yes.
EDIT2
Perfect, I've tagged all Compilations with "1" and the smartplaylist filtered them out.
Is there anything similar that can be done for Live albums for the same "wrong year" reason? I see there is no specific tag for that, so I tried {"notContains": {"album": "Live"}} , but many Live albums often do not have the word "Live" in the title (while others do and are not Live albums).

[certuna]

This will come when the new scanner + support for more tag fields is done, the releasetype tag has this information ("album;live" , for example). When that's supported, you'll be able to do something like {"isNot": {"releasetype": "live"}.

Unfortunately, this tag is usually only populated on the album/release level (by Picard, etc), so individual live tracks, such as bonus tracks on a studio album, can not be caught that way.

For anyone looking into smart playlists i made a sample playlist generator based off a user spotify activity and music library.

It would be very interesting, but for me this point is a show-stopper:

!!It is important that you have all the artists folder at the root of your library!!

Long before music organizers existed I sorted all my artists into about 75 macro-genre folders for easy finding. So my hierarchy is /music/[genre folder]/artist/album. Musicbee, Navidrome, and basically every other tool I use have no problem with that.

I may implement /music/genre/artist later maybe, at the moment my script supports /music/artist/song, music/artist/album/song, music/artist/album/cd/song

At the actual state the important thing is the /music/artist path.

And I had a lot of problems with Spotify rate limiting, but kinda solved it putting a lot of sleeps in the code.

[janaxhell]

I will subscribe to your git and wait :)

[kgarner7]

On a related note, MusicBrainz also has tooling for creating playlists via Subsonic api, available https://github.com/metabrainz/troi-recommendation-playground (this is useful if you have tracks tagged with mbid).

[blastbeng]

I will subscribe to your git and wait :)

Next step is to create a docker image so people don't need to install python and deps by theirselfs.

[blastbeng]

I will subscribe to your git and wait :)

I refeactored the code, now it works just by using subsonic apis :) So no matter how your music library is organized.

[janaxhell]

Great! Later I will look through the docker-compose!

[pr0927]

This is the most roundabout thing, but I've been using Feishin on desktop - which is phenomenal - and making smart playlists in there. They then appear as playlists in Navidrome, on the web and all (reverse-proxied website pointing to the instance).

I don't think this is ideal, of course - would be great to have a built-in GUI for this, but it's a nice workaround for now - somehow could never get the text file approach to work.

Just as a heads up, feishin has preview button for the smart playlists that gives you the code for the nsp file (missing the sort and limit settings)
You can use that to create the nsp files as well

[RedKage]

I'm discovering Feishin thanks to you guys, and as you said, this is indeed a phenomenal client!

[garyo]

Just wanted to chime in here and say I'd love to see multi-field sort in smart playlists. I have a "Favorites Rotation" with not-recently-played favorites, like this:

{
  "all": [
    {"is": {"loved": true}},
    {"notInTheLast": {"lastPlayed": 60}}
  ],
  "sort": "lastPlayed",
  "limit": 500
}

which works great, but I'd prefer if it kept songs from the same album (or artist) together, not randomly jumbled. So I'd like to see "sort": ["lastPlayed", "sortAlbum", "sortArtist"] or something like that.

[deluan]

So I'd like to see "sort": ["lastPlayed", "sortAlbum", "sortArtist"] or something like that.

@garyo: yes this is planned :)

[relink2013]

This may be a ridiculous question, and I hope it's ok to ask it here but it seemed relevant.

Would it be possible to have smart playlist templates that are assigned keywords? Users can create their own smart lists by just putting certain keywords in the title of the playlist.

Just as an example since all major streaming services like to use the word "radio", I'll go with that.

So you can name the playlist whatever you want, but if it ends with [Radio] then that keyword will trigger Navidrome to pull the template associated with the keyword [Radio].

It will then automatically assign the playlist only to the user who created it, and as they add music the playlist will automatically grow with similar artists and new tracks from artists in the playlist. Contents of the playlist can be modified periodically based on favorites, number of skips, play count, etc.

It would also be great if every time the playlist was updated on the backend it would re shuffle all the tracks, this way your "Radio Station" doesn't start in the same place every time.

The inspiration for the idea came from the fact that every compatible client app does things differently, so to have a consistent experience this would have to be done on the backend, and not reliant on the client apps to support it.

You could script yourself something that builds these.
First: I think smart playlist are only given to admin user/ first user you create. I don't think smart playlist can be added to other users only at the moment. So every time it updates it will just give it to the admin account.

What I'd do is make a folder available editable by different users and mount that folder to add to library.
There's other programs to create smart playlists too that may help your end users out if they want to give it a shot.

Second: I don't think individual user ratings or favorites are taken into the database yet.
So only admin users ratings and favorites will work with smart playlists at the moment.

It may be possible in future update though.

@SickProdigy:

First: I think smart playlist are only given to admin user/ first user you create. I don't think smart playlist can be added to other users only at the moment. So every time it updates it will just give it to the admin account.

Yes, but you can change the smart-playlist ownership in the UI, and then it uses the new owner's data when updating.

Second: I don't think individual user ratings or favorites are taken into the database yet. So only admin users ratings and favorites will work with smart playlists at the moment.

Not really. All users have their own ratings. favorites, play counts, etc... But as I said above, the Smart Playlist is calculated with its owner's data. You just need to change the owner.

@relink2013:

It will then automatically assign the playlist only to the user who created it, and as they add music the playlist will automatically grow with similar artists and new tracks from artists in the playlist. Contents of the playlist can be modified periodically based on favorites, number of skips, play count, etc.

Have you tried using Feishin to create/edit smart playlists? Your users can use it with their own account and create the playlists automatically, without the trouble of changing ownership as I explained above.

I have never even heard of that until now! That looks absolutely awesome! Are there other projects like that too?

[deluan]

I have never even heard of that until now! That looks absolutely awesome! Are there other projects like that too?

Only Feishin has the Smart Playlist editing feature, as this is a Navidrome exclusive feature, not available in the Subsonic API, and Feishin uses Navidrome API.

But there are quite a few apps out there compatible with Navidrome, for all tastes. Take a look at this non-comprehensive list: https://www.navidrome.org/docs/overview/#apps

I'm loving Smart Playlists! It was just what I needed to create new mixes. God sent, thank you.

I have either found a bug or a limitation: On a new Smart Playlist file, when referencing a playlist by ID (taken from reading the database file), it works as long as it isn't another Smart Playlist. For example:

{
  "comment": "Last Year's Best Rated",
  "all": [
   {"inPlaylist": {"id": "631db380-38ce-4b93-947a-abae8357da50"}},
   {"gt": {"rating": 3}}
  ],
  "sort": "random"
}

Works as long as the ID belongs to a regular playlist, if it belongs to a Smart Playlist it's not working. In the example, it references a Smart Playlist for songs added {"after": {"dateadded": "2024-03-01"}}, which is working fine.

I have the latest navidrome release. As well as Feishin's, for some testing there (it behaves the same way).
I've done multiple other playlists using notInPlaylist or inPlaylist. All of them work, get updated, some have a much longer list of regular playlists. All good.

Any insights on this would be greatly appreciated.

@TheMemoman it's a known thing and just badly documented.
If you want to reference a smart playlist it needs to be set to 'public'. Then everything works as expected.

Hello, I am new at navidrome so thank you for the great software.
I am having an issue with some smart playlists where the contains or endsWith condition is not respected.
Example:

{
    "name": "Three Underscores Test",
    "all": [
        {
            "startsWith": {
                "comment": "pop"
            }
        },
        {
            "endsWith": {
                "comment": "___"
            }
        }
    ],
    "sort": "datemodified",
    "order": "desc"
}

or similarly

{
    "name": "Two Underscores Test",
    "all": [
        {
            "startsWith": {
                "comment": "pop"
            }
        },
        {
            "contains": {
                "comment": "__"
            }
        }
    ],
    "sort": "datemodified",
    "order": "desc"
}

These both will only grab songs that have a comment starting with "pop" but will not care for two or three underscores in the comments.
I have a feeling underscores get ignored at some point in this computation. Is there a way to unignore them?

Thank you!
