My favourite band ever is Green Day. Quiet you they're sexual and make my hears copulate and create little green men with blue couch disease. yeah you heard me, yellow.
Anyway the rest in no particular order because that's hard...
The Distillers
The Dresden Dolls
The Used
Hole
Billy Talent
Madonna
Enya
Jack Off Jill
Taking Back Sunday
Rancid
Three Doors Down
Kate Bush
Kill Hannah
Less than Jake
Hmm yes I know some of them aren't actually bands but people but you suck and I can make you explode and I'm not listening! *dances* Oh my Rocket!
