The music selection is poor and too much focused on pop music. To progress in the game I'm forced to play music that I don't like, with too much emphasis on the vocals instead on other rhythmic or melodic parts. The fact that I also have a limited number of times I can play before I have to wait hours to unlock random content is too restrictive. I don't think I'll ever spend money on this app with it's lacklustre playlist and restrictive gameplay. The team also doesn't seem to care about reviews
