I always enjoyed playing these games. I only played SongPop 2 though. You had to guess the singer, song, and other things like that to get more in-game currency. The more you get right the more things you get to do. Also, you go by genres as well until you can successfully get all the questions right. At least, that is what I remember when I played it.
