Consider an album containing 5 tracks. Each track is by a different artist. i.e. all tracks have the same entry for Album tag and different entries for artist tag. Elisa displays these 5 as separate entries in the album view. Why can't tracks be simply grouped based on album tag? Why unnecessarily involve the artist tag for this? PS: The 'album artist' tag is not a solution as that might not make sense in all cases.
This is a bug that was fixed in the 19.12 version which was released yesterday. *** This bug has been marked as a duplicate of bug 409147 ***
