Spotify Integration : Show which playlists already contain the track

[tomjcb]

It would be really useful if the Add to Playlist feature could indicate whether the current track is already present in each playlist, similar to how Spotify handles it.

When opening the playlist selector in Spotify, playlists that already contain the current track are visually marked with a checkmark. This makes it easy to see at a glance where the track is already saved and helps avoid accidentally adding the same track multiple times.

Here's a GIF showing how Spotify handles this:

Sorry for the French UI in the recording 😄, it's just to give an idea of how the feature works.

I'm not sure whether Spotify's API makes it easy to retrieve this information without requiring too many additional requests, but if it's feasible, I think it would be a really nice improvement to the current playlist integration.

Thanks for separating this from the playlist-writing bug, and the French UI is no problem. Checkmarks for playlists that already contain the current track would make the picker clearer and help avoid duplicates. This wasn't added in 1.0.191. The main things to check before implementing it are how much playlist data Spotify exposes for your account and how to avoid fetching every playlist's contents each time the picker opens. I haven't verified that feasibility yet, so I'll keep this as a feature request rather than promise a release date.

@tomjcb, the visual-feedback fixes are now in Notchy 1.0.193. Existing tracks update their checkmark without showing a new-add success message. Membership scanning visits each playlist before following additional pages and publishes known results as they arrive; a pending scan also preserves a checkmark confirmed by your click until the next fresh picker open.

Regression tests cover all three defects, and the full unit suite plus runnable inactive-app checks passed. Please update, leave Playlist Checkmarks enabled, and try the same playlists. Spotify account/API behavior still needs your confirmation, so I am keeping this open.

@vishvavariya Thanks for the quick follow-up and for pushing another fix so fast!
I’ve just updated to 1.0.193 and retested the same scenario, but unfortunately it seems to have regressed on my side.
The playlist checkmark still doesn’t appear for tracks that are already present in a playlist, and more importantly, duplicate prevention no longer seems to work either: I can add the same track to the same playlist again, even when it’s already there.
So compared to 1.0.192, where duplicate prevention was working but the visual feedback was missing, 1.0.193 seems to have brought back the duplicate-add behavior as well.
I recorded a short video showing the issue, which I’m attaching below.
Thanks again for the responsiveness — I really appreciate how quickly you’re iterating on this feature!

@tomjcb, thanks for retesting and showing that 1.0.193 still allowed duplicates. Notchy 1.0.194 adds further corrections to both identity and membership scanning:

• Prefer the exact Spotify track URI and distinguish different album/track editions with otherwise identical metadata.
• Keep scanning other playlists if one playlist fails, so that failure cannot suppress their checkmarks.
• If an item cannot be identified on any page, keep membership unknown and block an addition that could create a duplicate, rather than treating an incomplete scan as proof the track is absent.

Regression tests cover failed playlists, pagination, exact track identity and zero add requests when membership is unknown. Those are offline request tests; your live Spotify account still needs confirmation. Please update, leave Playlist Checkmarks enabled, and try the same track/playlists. If it still fails, the track's Spotify link and whether the picker says present, absent or unavailable would help. Keeping this open.

@vishvavariya Just updated to 1.0.194 and retested everything with Playlist Checkmarks enabled — I can confirm that everything is working properly now! 🎉

The checkmarks correctly show which playlists already contain the track, and duplicate additions are properly prevented.

So everything seems to be working exactly as expected on my side now.

Thanks again for the incredibly quick fixes and for implementing the suggestion so fast! Really appreciate the responsiveness 🙌

@tomjcb, thanks for retesting and confirming both the checkmarks and duplicate prevention now work with your Spotify account! That resolves the reported behavior on your setup. I appreciate you sticking with the fixes and sharing the recordings.
