If I load the song from external hard drive and then turn out the drive, the song is still in library.

This is because we stopped scanning the library on bootup. The library needs some work in the area of multiple library folders and removable libraries (ipods, external drives, etc.) so this area needs work.

I'm seeing this even with the internal drive. If I move or rename files, they never show up in the "Missing" list. I just get errors when I try to load and play them

I had considered to move missing tracks directly to the missing tracks list, if you try to load it. But I have thought that it is not a good idea to let a song disapear when the user whants to do something with it.

We need a good solution especially for crates and playlists. There is no reason to partly destroy a playlist only because a track is temporary unreachable.

What could be the best behavior?

• Just leave the missing tracks where it is?
• Mark the song as missing at original place "grayed out"
• To let the user decide "Track is missing. Do you wish to move it to missing Tracks folder ..."

Daniel -- I agree.

What if we had a status column that had icons in it to indicate things like:

• track is missing
• track has been analyzed
• other things? failed to parse? track is low quality?

Also, missing tracks don't get remove from the crates/playlists -- they
just aren't shown. If the track is marked not-missing at some point then it
will re-appear where it was. I agree the user might go looking for a track
and be confused that it isn't in the playlist where they left it, so I
think you're right that we should fix that.

Update:

• Missing Tracks are not removed from Playlists.
• Tracks are only marked as missing by the library scanner

TODO:

• We should update the missing state at various track operations. Like adding to a playlist, loading to a deck.
• The "Add Random" button should check the path and should not add missing tracks.
• Adding a Missing track to a playlist/crate should be still possible (the user may collect missing tracks for some reasons)
• We should avoid adding missing tracks to Auto DJ. This has party stopper potential.

I have move the prio up because since "Auto DJ crates" this is more important.

I'm not sure but touching every file to check it is missing when we add a list of files to a specific crate. That sounds like we would hit a huge performance hit when all we want to do is a simple sql query.

As for AutoDj. It should handle the missing tracks gracefully. We can never relly on track in the autoDj playlist being still available (that can change between the time it was added and when it is supposed to be played).

For the use case of removable devices it might be worth scanning the track folders for availability and not each single track ...
