Terrible. Perhaps the worst music app of all time. Don't believe this 4.8 star rating, they literally own the app, they can say whatever they want about how "great it is". If you're all for losing your owned music and having your playlists being completely rearranged without you doing so, than this apps for you. It's honestly shameful that they took away Google music and gave Android users this as something "acceptable". It's stupid, poorly designed and a truly appalling replacement.
