Apple Music's convention of putting guest artists/vocalists in the track titles drives me a little bit crazy.
It messes up your 3rd party/Last.FM stats, it pollutes track titles with metadata that shouldn't be in there, and it's just plain ugly. On some albums, every track has a guest artist and you're presented with this huge wall of text.
An example album. Not the worst example, but still annoying. It really gets unwieldy when it's the whole album, or when the guest artists have long names.
iTunes/Apple Music have always struggled with how to represent more than 1 artist in metadata. Seems they should either make Artist able to hold n artists instead of only 1. Or they could add a new metadata field for guest artists/vocalists; you could toggle the visibility when you're curious, and hide it to be more minimalist. The song should appear in your library under both artists. AM does do this to an extent on the AM artist pages, with the "appears on" section, but their use of that seems inconsistent.
In the meantime, on desktop you can edit the tracks back to normal. I usually copy it over to the "Comments" field. But this is labor intensive, plus AM ignores your library metadata when you listen to stations.
/r/apple is going indefinite. Awesome stuff. I am guessing there is a heavy overlap of /r/apple users and Apollo users.
