There's some palm muting in it, which is kind of optional.
The rhythm isn't hard to pick up on, and it's fairly easy to play. 
Note: The ~ means to let it ring.

Capo on 2nd fret

________________________________________________
I just play this in the intro, since it's what's played in the background with the 
little solo bit. It's also thrown in a few other place in the song.
