The tab for this song on here was completely wrong so here's simply how to play it right.
Intro:
-------------------------------------------|
-------------------------------------------|
--4-4-2----------------4-4-2---------------|
--4-4-2----------------4-4-2---------------|
--2-2-0-------2--5--2--2-2-0--2--5--2------|
---------2--5-------------------------5--2-|

Verse/Chorus:
------------------------------------------|
------------------------------------------|
--4-4-4---2-2-2---------------------------|
--4-4-4---2-2-2--2-2-2--4-4-4-------------|
--2-2-2---0-0-0--2-2-2--4-4-4-------------|
-----------------0-0-0--2-2-2-------------|
That progession is played throughout nearly all the song. It's just mixed up with a
different rythm (listen to the song you'll get it) The intro part is occasionally played again.
