this song's a bit tricky, the best advice I can give is just play it until you get it
and most of all, have fun with it :)
main riff:
E -----------------------------------------------|
A ---10-10---10-7-7------------------------------|
D ---------9---------9-7-9-9------10-10----------|
G ----------------------------7-9--------9-12----|
chorus:
E ---8----------8---5-----8---10-10-10-10-10-10-10-10------|
A ---------------------------------------------------------|
D ---------------------------------------------------------|
G ---------------------------------------------------------|
and that's basically it. listen to the song for the exact rhythm
