I worked out this intro in a couple of minutes by ear,
and it's not too hard to figure out.
This is the way i play it, it could sound different to
some people, but it could also sound correct to some people.
Everyone has their own opinion, this is my first tab btw.

You should be able to figure out the pattern of the intro
on your own it's not too difficult, just listen to the song.
