Girl On Fire - Alicia Keys

Verse 1:
A                                 F#m
She's just a girl, and she's on fire
D                      E    
Hotter than a fantasy, lonely like a highway
A                                      F#m
She's living in a world, and it's on fire
D             A                 D                      E
Filled with catastrophe, but she knows she can fly away

Prechorus:
A   F#m
Oh, she got both feet on the ground
C#m                        E  
And she's burning it down
  A F#m                           
Oh, she got her head in the clouds
C#m                         E
And she's not backing down

Chorus:
                  A
This girl is on fire
F#m                 C#m 
This girl is on fire
E                  A
She's walking on fire
F#m                C#m   E 
This girl is on fire

Verse 2:
A                                    F#m
Looks like a girl, but she's a flame
D                                
So bright, she can burn your eyes
E                            
Better look the other way
A                                            F#m
You can try but you'll never forget her name
D         A  
She's on top of the world
D               E
Hottest of the hottest girls say

Prechorus 2:
A   F#m                            C#m
Oh, we got our feet on the ground
                       E  
And we're burning it down
  A F#m                         C#m 
Oh, got our head in the clouds
                       E
And we're not coming down

Bridge:
D                               E 
Everybody stands, as she goes by
                                              D
Cause they can see the flame that's in her eyes
                                           C#m
Watch her when she's lighting up the night
             A                F#m 
Nobody knows that she's a lonely girl
               C#m 
And it's a lonely world
                    D           A          D  E
But she gon' let it burn, baby, burn, baby

Bridge 2:
E A F#m   D        E  
Oh,     oh,    oh
  A F#m    C#m    E     
Oh,     oh,    oh
  A F#m    D         E
Oh,     oh,    oh
  A F#m    C#m    E
Oh,     oh,    oh

A                                 F#m
She's just a girl, and she's on fire
