The main theme, repeated throughout the song.

e-------------------------
B-------------------------
G-7-----7-----9-----------
D---8-8---8-8-------------
A-------------------------
E-------------------------

These power chords are played during the verses and bridge of the song.
 E5 F#5 G5    F#5 G5 A5    A5 B5 C5

B----------------------------------

D-2-4-5--------4-5-7--------7-9-10-
A-2-4-5--------4-5-7--------7-9-10-
E-0-2-3--------2-3-5--------5-7-8--

Before the song loops, the C5 chord is pushed to the background due to 
the theme slowly becoming louder.

The guitar lick heard before the second verse.  
Slide slowly from 7th fret to 5th fret.

For the chorus, the main theme moves up a half-step, and is followed 
by four note progression.  The chords are:

  E    F#   G
e-0----2----3--
B-0----2----3--
G-1----3----4--
D-2----4----5--
A-2----4----5--
E-0----2----3--

On the first time through, play this three times:

e----------------
B----------------
G-8-----8-----10-
D---9-9---9-9----
A----------------
E----------------

Followed by this progression:

e--------------
B----8-11------
G-10------8----
D--------------
A--------------
E--------------

The second time, play the theme variation, then this progression:

e--------------
B-------10-13--
G-10-12--------
D--------------
A--------------
E--------------

After the bridge comes the third verse.  Play this lick.  Bend the 
12th fret halfway during the first stroke,
then bend it further on the second:

e-12b-10-10-12b
B--------------
G--------------
D--------------
A--------------
E--------------

The last lick comes before the second chorus, and sounds like this.  
Hold the last note for a long time!:

e-18b----18-15------------------
B--------------18-15----------17
G--------------------17-15-17---
D-------------------------------
A-------------------------------
E-------------------------------

Last but not least, the bass part.  It's very simple:

D-------------------------------------------------------------------
G-------------------------------------------------------------------
A-------------------------------------------------------------------
E-0--000--0--0030-3--333--3--3353-5--555--5--555--5--555--5--555----

Chorus bass.  I'm not very sure about this as 
it's difficult to hear in the mix:

D------------------------------
G------------------------------
A-----------------2-222--------
E-0--000--4--444---------2-222-
