This is my first tab, but I'm pretty sure it's correct.
DON'T forget to tune A up to B. It can be played with standard tuning, too, but this is 
easier.

The main riff goes like this
--------------------------------|
--------------------------------|
0---3-0-3-3-0-3-0---3-0-3---5---|
--------------------------------|

And every once in a while it switches to this
--------------------------------|
--------------------------------|
0---3-0-3-3-0-3-0---3-0---------|
------------------------3-2-1-0-|

That's it! Easy song, but still catchy! Good luck!
