There's waay to many to even begin naming bands. . . So I'll start with here. . .and it varies from heavy to poppy. . .BIG TIME.
Black Sabbath, Metallica, Green Day, MxPx, Godsmack, Nirvana, Foo Fighters, Rage Against The Machine / Audioslave, New Found Glory, Silverchair, Pink Floyd, Portishead (genius use of sampling!), The Beatles, Oasis, Superdrag, Sublime, Slightly Stoopid, Tribal Theory, Common Kings, Dirty Heads, The Green, Iration, Early November, Senses Fail, Finch (RIP), Fitz & The Tantrums, The Roots, Me First & The Gimme Gimmes (THE greatest punk rock cover band. . . .EVER!), Papa Roach, All American Rejects, Unwritten Law, Smashing Pumpkins, Linkin Park, The Cure, Aquabats, No Doubt, Taking Back Sunday, Guns N Roses (Say what you will bout him. . .I think Axel is a musical genius. . .if he wasn't such a douche and crazy!)
I'd have to go through my ipod. . . .and about 15G of harddrive at home. . . .but that's just some of my music. . . .And I'm a frigging hip-hop DJ. . . .
