Guitar Sidekick

So my rommate recently spent a night playing Guitar Hero in a friend's dorm, and the next day went out and dropped 80 bucks on guitar hero 2. We're planning on getting a second guitar and guitar hero 1, but in the meantime we're doing our best to unlock songs and characters and what not. All I can really say is, anyone who can play any of these songs on the "Expert" mode is ridic ulous. I have a hard enough time playing some of these songs on Medium, and I can only get through a few of them without failing on Hard. The game itself is pretty addicting, and the songs are pretty fun to play.
