here's how i play it... it sounds a little better.

Main Riff (not the exact number of times to strum, but you'll get it)
G----------------|
D----------------|
A--5555-77-------|
E----------5555--|

Verse
G---------------------|
D-----------55555432--|
A---------------------|
E--33333333-----------|

"Chorus" (those are tens below)
G------------------------------|
D------------------------------|
A--101010101010-9-7------------|
E-------------------10-777777--|

After Chorus
G-------------------|
D-------------------|
A-------7---3-------|

it should be easy to figure out where everything goes. it's only hard cause it's played fast as hell!
