Any song that I'd want to be in Guitar Hero 6, I'd rather see in Rock Band. But these songs would be pretty fun:
Paradise City -- Guns N' Roses (will never happen because Axl's a dickhead)
Champagne Supernova -- Oasis (this song is really technical if you pay attention to it)
Guster -- Satellite (fun guitar riff, great bass and drum parts, and the vocals would be easy as hell)
Maggot Brain -- Funkadelic
Like Suicide -- Soundgarden
Two Tickets to Paradise -- Eddie Money
That Smell -- Lynyrd Skynyrd
All You Zombies -- The Hooters
