Remove tracks where there is no file available from the database, remove empty albums from database
What is the problem you are facing?
When you select files and delete them in the admin > library view, the files are removed from the disk but the tracks still appear in the web UI. When there are no more playable tracks in an album (because they've all been deleted), the album still appears in the web UI
What are the possible drawbacks or issues with the requested changes?
None.
