Ah wow. I don't like how Dave said that statement. Just because he is in the Foo Fighters, doesn't give him the right to have a big head and say what defines rock music. Music is music and if Linkin Park use samples their music, who cares? Someones got to trigger them. Someones got to have the musical timing and talent to trigger them. It's still music, it's still an art. Dave needs to take a step out of his arse and realise that rock music isn't just drums, guitar, bass & vocals.
