I have both Apple Music and Spotify, and i also dislike Apple's Music app; First, it deleted ALL my playlists on a random day for no apparent reason, and i couldn't restore them from backups because apparently the playlists are stored in the cloud or whatever and not in a local file. Also, after converting my personal library to "iCloud", Apple replaced all my specific versions of songs with crappy alternative versio…
I've had spotify for 5 years now and it's always felt just as unpolished as when I first got a subscription, which is unfortunate.
