Mind bogglingly bad for a modern app. There are just a ton of basics around managing your personal library that this app completely misses. From being able to just view the songs you have favorited from an artist to accessing your playlists offline (?!?!?!) this app completely misses the mark. These aren't complex features either. This is just the basics. Offline mode in particular is garbage for trying to organize and play your music in any meaningful way. Canceling because of this trash.
