Intro: Dm (add a thumb on the top strings)

Dm
Be careful making wishes in the dark, dark
F
Can't be sure when they've hit their mark
Dm                                     F
And besides, in the mean meantime I'm just dreaming of tearing you apart

Dm
I'm in details with the devil
F
The world can't ever get me on my level
Dm
I just got to get you out the cage

I'm a young lover's rage 
F                  
Gonna need a spark to ignite
Dm
My songs know what you did in the dark

Chorus:  

Dm
So light 'em up, up, up
Fm
Light 'em up, up, up
F
Light 'em up, up, up
C
I'm on fire

Dm
So light 'em up, up, up
Fm
Light 'em up, up, up
F
Light 'em up, up, up
C
I'm on fire

Dm    F                 C    
Whoa, oh, oh, oh, whoa, oh, oh in the dark, dark
Dm    F                 C    
Whoa, oh, oh, oh, whoa, oh, oh in the dark, dark

Dm
The writers keep writing what they write
F
Somewhere another pretty vein just dies
Dm                                   
I've got the scars from tomorrow and I wish you could see
F                                     
That you're the antidote to everything except for me
Dm
A constellation of tears on your lashes
F                                  
Burn everything you love then burn the ashes
              
In the end everything collides
                                            
My childhood spat back out the monster that you see
Dm       
My songs know what you did in the dark

Chorus: 

Dm
So light 'em up, up, up
Fm
Light 'em up, up, up
F
Light 'em up, up, up
C
I'm on fire

Dm
So light 'em up, up, up
Fm
Light 'em up, up, up
F
Light 'em up, up, up
C
I'm on fire

Dm    F                 C    
Whoa, oh, oh, oh, whoa, oh, oh in the dark, dark
Dm    F                 C    
Whoa, oh, oh, oh, whoa, oh, oh in the dark, dark

Bridge:

Dm       
My songs know what you did in the dark
Dm       
My songs know what you did in the dark

*drum roll*

Chorus: 

Dm
So light 'em up, up, up
Fm
Light 'em up, up, up
F
Light 'em up, up, up
C
I'm on fire

Dm
So light 'em up, up, up
Fm
Light 'em up, up, up
F
Light 'em up, up, up
C
I'm on fire

Dm    F                 C    
Whoa, oh, oh, oh, whoa, oh, oh in the dark, dark
Dm    F                 C    
Whoa, oh, oh, oh, whoa, oh, oh in the dark, dark

Dm    F                 C    
Whoa, oh, oh, oh, whoa, oh, oh
