I need some help from Rock Band enthusiasts. I bought this game (Wii version) for my kids this Christmas but we only seem to be able to get about a dozen songs. This game says there are many more than that but we only see the same dozen songs or so. Even picking a random song gives us the same ones over and over. Any clues? Thanks.

Never mind. We figured it out. Had to do the tour to unlock songs. Thanks anyway.
