Very fun game, you get exactly what you expect. The game randomly selects a song from your library and gives you five choices of what it could be. The longer you take to answer the less points you receive. As time runs down the game will also eliminate answers to help you.
The one negative is there is no way to lose unless you quit. If you run out of time it goes to the next song, and if you get one wrong it's just -250 points...
