This is a single album, yet iTunes shows it as a number of different albums with different titles. I’ve sorted by album so each title should be grouped, but you can see there are four different titles for tracks in the first grouping. And that first group of tracks, which is hanging together as an album, has track numbers in a seemingly random order.
Frank Sinatra is listed as the artist for all these tracks, sometimes with others. But if I view this album in a playlist by Artist, the only artist listed is Cole Porter.
I’ve seen that iCloud Music Library changes tags and artwork. Rather than assuming that your tags, the ones you may have manually changed, are canonical, it just decides what the tags should be on your music. For example, yesterday, I deleted composer names in all the music in the Rock genre in my library. I don’t care about composers for that kind of music; those tags just get in the way when I browse using the column browser. But, today, all the composers are back for those songs.
It’s still failing to provide correct metadata for songs from Apple Music, not just ripped or third-party tracks. It’s too bad, because a lot of Apple Music’s features — like offline playback and playlist creation — require an iCloud Music Library subscription.
My metadata system isn’t complex, but I worry that any cloud service will attempt to “correct” it.
Update (2015-12-17): Joe Rosentseel:
iCloud Music Library is the reason I stopped using Apple Music before the free trial was even over.
