I doubt this is accurate, but it sounds great when i play it along with the song.

Also, some distortion should be used, i'm not sure what though, but just heavy 
i suppose.

Main Riff:

G---------------|
D---------------|
A---7--7----7---|
E-5---5-6--6-66-|  You may think i have missed out some notes, but the notes youre 
of are played on guitar.

Chorus 1

G--------------------|
D--------------------|
A---7----------------|
E-5---5-00-2-0-3-0-4-|  You should know the timing for that last part, if you don't you 
aren't listening to the song.

Chorus 2

G--------------------------------------|
D--------------------------------------|
A---7----------------------------------|
E-5---3-5/77-5-3-5/8-8-88-00-2-0-3-0-4-|
