I use a pick and brush the top of the strings--its a bit hard but it gives the song much 
more real feel.

Listen closely to how the notes are played cause its kind of a tricky rhythm.

Important: Palm-mute throughout the song

Come in at 0:17 during the Intro, into Verse 1

G--------------------------------------------------|
D--------------------- 88888-----------------------|
A-----1010101010\6666-------------66666------------|
E 8888------------------------4444------6666\4/6---|x8

(those are 10s, not 1's and 0s ^^^)

Play until 1:29 (Into pre-chorus part 1):

G-------------------------------------------------------------------------|
D-------------------------------------------------------------------------|
A-------------------------------------------------------------------------|
E-888888/10101010101010/11(11)11(11)11(11)11-\66\4444444-/8888\6666-------|

(You don't have to play the string exactly as many times as indicated, but understand
that you're not simply plucking one then moving on--there is a rhythmic feel to it that
needs multiple hits of one string.)
