Verse

C              G
There's a fire starting in my heart
B                               G                   B
Reaching a fever pitch and it's bringing me out the dark,

C              G
Finally, I can see you crystal clear
B                              G                  B
Go ahead and sell me out and a I'll lay your ship bare

C                       G
See how I'll leave with every piece of you
B                       G                  B
Don't underestimate the things that I will do

C              G
There's a fire starting in my heart
B                               G                   B
Reaching a fever pitch and it's bringing me out the dark

Pre - Chorus

Ab           Bb                  G
The scars of your love remind me of us
             Ab
They keep me thinking that we almost had it all

Ab           Bb                       G   
The scars of your love, they leave me breathless,
             Ab
I can't help feeling

Chorus

                     C               B
We could have had it all
               Ab                    B              Ab
Rolling in the deep

                 C              B
You had my heart inside of your hand
        Ab               B           Ab
And you played it to the beat

Verse

Baby, I have no story to be told, 
But I've heard one on you and I'm gonna make your head burn, 
Think of me in the depths of your despair, 
Make a home down there as mine sure won't be shared, 

Pre - Chorus

The scars of your love remind me of us,  
They keep me thinking that we almost had it all,  
The scars of your love, they leave me breathless,  
I can't help feeling,

Chorus

We could have had it all,  
Rolling in the deep,  
You had my heart inside of your hands,  
And you played it to the beat, 

Verse

Throw your soul through every open door, 
Count your blessings to find what you look for, 
Turn my sorrow into treasured gold, 
You'll pay me back in kind and reap just what you've sown, 

Chorus

We could have had it all, 
Rolling in the deep, 
You had my heart inside of your hands,  
And you played it to the beat, 

HOPE YOU LIKED IT!!
