Some begginner songs for guitar?

I'm into system of a down, foo fighters, queens of the stone age, deftones. All sorts really. I have literally just started playing guitar, but apperently i'm picking up quite quick. I'm a drummer and i pianist, but want to expand my musical knowledge. So can anybody give me a good but easy song for the guitar, i'll watch on youtube and try to play along or something. When i say easy, i mean pretty straight forward, i'm trying to learn 'dear prudence' by the beatles. Is'nt go to well to be honest.
