Easier to Run is definitely my vote.
Next would be Figure.09. And I say that only because of the bridge of the song (screaming and rapping part). I could listen to that all day it's amazing. I can't imagine any better of a rapping voice and screaming, Chester just blows any other screamer out of the water (I don't know if he can still scream like that). In fact, I dislike any other screaming other than Chester's.
