Orphaned media files
Steps to reproduce
I believe this was caused due to me upgrading an album from mp3 to FLAC. Import an album as MP3, properly tagged, as in-place. Then, replace the album with a FLAC version, properly tagged. Import files again in-place, afterwards I've pruned and 'check_inplace_files' as well.
Everything seems to have mostly worked, but one track is leftover on a 'separate' album, same name and artist.
And notice here that the second album (the one with one track) has one track. It's track page shows no information:
What is expected?
I should only see one instance of the album.
