A good app. You can enjoy this game. But somehow there's an annoying sound in audio and bgm of this game and if you turn it off the game will becomes boring. I especially liked the Guitar mode but somehow it doesn't match to the audio. The app was kind of laggy. And if you are looking for offline games then I don't recommend this to you because this game required an nternet to get the prizes, although you can still play this offline and you need to download other songs too.
