Good stuff I would pay a lot of money for. . .

1st I know its not Rock but with Freeze Pop in their I know it can be done.

1st A-ha. The most recent stuff would fit in just fine.

2nd Pet Shop Boys. It would be fun to sing along, and pretend you can play a keytar. :P

More realisticly though Icicle Works would be a blast!

There are some modern choices that make sense . . . Like Shinny Toy Guns and Arcade Fire.

Pet Shop Boys would be awesome but I don't know how many songs would work with Rock Band...maybe some stuff from Release? They used a bit more guitar on that album if I recall...
