It's good and all, but if you're attempting to look at a preview before playing the song, good luck trying to let the game decide when to send you back to the menu, it'll just stay in the song that you picked, even long after it ended. Also, when there are too many notes on the screen, the game can't comprehend what's happening, so it stutters so badly to the point where the song isn't even fun to play. Smule will most likely say that it's my phone, but nope, it's not, others do the same thing.
