This song pretty much revolves around a simple two chord structure, the first being a 
Em-Dsus2-Em and the chorus is G to F#.
Definitely listen to the song because they really lay on the texture.

             Em Dsus2 Em Dsus2    Em Dsus2 Em
Tell me what sin         replaces love

 Dsus2  Em Dsus2 Em Dsus2 Em Dsus2 Em
I wanna know,       right now

             Em Dsus2 Em Dsus2    Em Dsus2 Em
Tell me what sin         replaces love

 Dsus2  Em Dsus2 Em Dsus2 Em Dsus2 Em
I wanna know,       right now

(continued with higher energy, optional walk up is E-F#-G-F#-E)

Imagine yourself on a mountain
Mountain discovered with flowers
Flowers discolored with horses
Horses distracted by stones
Stone distrusted with me
Then you might know what I mean

       G                                F#
'Cause I want to kick love right in its gut
G                      F#
Beat it and leave for dead
G                      F#
Wash my hands in the river
G            F#          Em
Lie down and die in your bed

(repeat 1st verse)
    G                 F#
The voice on the receiver
  G                     F#
Baby cry howlin' in the wind
 G                         F#
I don't wanna beg for your mercy
G                  F#         Em
I wanna know right know, what sin

Tell me what sin replaces love
I wanna know, right now
