This song is jun and kind of easy to learn. The other tabs are partially correct but not 
so im here to tell u the right way to play it. They use a pick for this song which does 
it easier to play unless u r kind of a fast finger-picker. Whatever, here it is...

First the guitar plays one thing, and then the bass and drums come in.
