If you have an album with multiple artists and want them to show up as one album, make sure all of the tracks have the same album artist property. This can be set when editing their metadata or inline the playlist if you add the album artist column. The album artist property is looked at first and if it doesn't exist the artist is looked at when checking whether tracks with the same album name belong to the same album.
