The song premiered an hour ago, sorry if the lyrics are not correct.
This is the easiest way I found to play it... if you want to make it better get rid of the capo!
There were D s n the bridge, between notes, but it's too hard to get them right
so I deleted them, sounds ok anyway.
Listen closely to the instrumental parts so you get the notes right.
UPDATE: VendelaHyde was right and I changed the Bm s to B7 s, you can still play Bm
Both chords are hard for beginners but there are easier and more ways to cheat a Bm than a B7
Cheat the B7 like this (from easiest to dificult):
B7 = xx4445, x21202, x24042, 
CAPO 3

[Intro]
C Am G C
[Verse]
       Em       Am
If you want it, take it
G                       C
I should have said it before
         Em       Am
Tried to hide it, fake it
G                   C
I can't pretend anymore
[Pre-Chorus]
Em             Am
I only want to die alive
G                       C
Never by the hands of a broken heart
Em                     Am
I don't wanna hear you lie tonight
  G                        B7
Now that I've become who I really am
[Chorus]
C       Em   G           C
 This is the part when I say I don?t want it
    Em             G           C
I'm stronger than I've been before
       Em   D           C
This is the part when I break free
      Am                   C
Cause I can't resist it no more
       Em   G           C

    Em             G           C
I'm stronger than I've been before
       Em   D           C
This is the part when I break free
      Am                   C   B7 C
Cause I can't resist it no more
[Verse]
         Em      Am
You were better, deeper
G              C
I was under a spell
       Em     Am
Like a deadly fear I am, babe
G                C
On the highway to hell
[Pre-Chorus]
Em             Am
I only want to die alive
G                       C
Never by the hands of a broken heart
Em                     Am
I don't wanna hear you lie tonight
  G                        B7
Now that I've become who I really am
[Chorus]
C       Em   G           C
 This is the part when I say I don?t want it
    Em             G           C
I'm stronger than I've been before
       Em   D           C
This is the part when I break free

This is the part when I break free
      Am        C          Am
Cause I can't resist it no more
[Bridge]
C*  G*      Em G* D* Am C* G*
(Our love baby, oooooh)
    Em
The thought on your body
  D     Am
I came alive
       C
It was lethal
       Em
It was fatal
      B7                Am  
In my dreams it felt so right
      C              Em     D  G     Em B7
But I woke up and preteeeeeeeeeeeend
    C
Oh baby
[Chorus]
       Em   G           C
This is the part when I say I don?t want it
    Em             G           C
I'm stronger than I've been before
       Em   D           C
This is the part when I break free
      Am                   C
Cause I can't resist it no more
       Em   G           C
This is the part when I say I don?t want it
    Em             G           C
I'm stronger than I've been before
       Em   D           C
This is the part when I break free
      Am                   C   
Cause I can't resist it no more
THERE IS THIS WEIRD OUTRO THAT ENDS ON G, JUST IN CASE YOU WANT TO PLAY SOMETHING.
