Replying to Guitar Hero Competition

So tommorow there's this big emo concert in my town, some bands like the saint alvia cartel, and attack in black are playing. Now I'm not a huge fan of all this music but there's a guitar hero competition. 5 bucks to play a song on, easy, medium, and hard. And at the end the winner gets a free guitar and meets the bands. I was wondering what songs you can get the most points for from GH 2? I need a combo of 3 songs. Thanks
