When you sort your music by Artist and if you happened to have a lot of compilation albums, you end up with “Various Artist” item that keeps your all compilation albums. Surfing songs on these compilation albums is not the best experience since you do not remember which album has which song. An option to expand albums according to Artists if “Artist” and “Album Artist” are different can be nice.
If there is “Album Artist” and no “Artist”, it will put the songs under Album Artist’s name.
If there is “Artist” but no “Album Artist”, it will put the songs under Artist’s name.
If there are values for both fields but they are different, it will put the songs under Artist’s name.
It would be nice, everybody would love that - but the way Plex currently stores Album Artist and Artist in its internal database is completely different (one is an indexed field, the other is a text field), it cannot combine these two in a meaningful way until they make major changes to the underlying db structure.
Compilation albums come with big issues in Plex, unfortunately - it was never designed for it in the beginning.
