Overloads cpu regularly causing battery to drain and device to overheat. Needs optimizing. Terrible bug when playing a long playlist (My Likes) the playlist truncates and I cannot advance to the next song without exiting the player mode and manually selecting the next song, listening to it and then repeating the process for every song I want to listen to after that. It's very frustrating and represents a slide backwards in terms of quality compared to Google Play Music.
