Song is really basic.  Same four chords for the whole thing...

CAPO on 3rd fret

G     D     Em     C

G
I have to keep reminding myself 
D
I'm not like anyone else 
Em
That's my face on my ID 
C
That makes me V.I.P. 
G
No one exactly like this 
D
No one with my fingerprints 
Em
No one can touch you like me 
C
No I can't fake what you see 

     G                                          D
They told me: "Girl, to get you're way, you've got to be a bitch!" 
     Em                                     C
They say : "A guy won't get the girl, if he's not filthy rich!" 
     G
You start with little changes, 
         D
'Til you don't know who you are 
    Em
Surround yourself with friends 
         C
Who only call you a superstar 
     G                 D                 Em        
Oh yeah (oh yeah), oh yeah(oh yeah), oh yeah (oh yeah)
 C
(Ready, set, baby let's go) 

    G
The sky is the limit 
       D
And I just wanna flow 
Em                       C
Free as a spirit on a journey of hope 
G                    D
Cut the strings and let me go 
      Em              C
I'm weightless, I'm weightless 
G                            D
Millions of balloons heading to the ground 
Em                           C
Weight of the world tries to hold us down 
G                   D
Cut the strings and let me go 
    Em                C           G
I'm weightless, I'm weightless,  
     D                Em            C
I'm weightless, I'm weightless, I'm weightless...

G
All the things I held in my fist 
D
If I don't let go, I don't exist 
Em
They've become the things that define me 
C
How I look and the things to buy me 
G
That's not important anymore 
D
I feel me rising off the floor 
Em                      C
Light as a feather, I'm carefree 
I'm weightless... 

    G
The sky is the limit 
       D
And I just wanna flow 
Em                      C
Free as a spirit on a journey of hope 
G                    D
Cut the strings and let me go 
      Em             C
I'm weightless, I'm weightless 
G                            D
Millions of balloons heading to the ground 
Em                           C
Weight of the world tries to hold us down 
G                   D
Cut the strings and let me go 
     Em                C          G    
I'm weightless, I'm weightless, 
     D                Em              C
I'm weightless, I'm weightless, I'm weightless 
G   D   Em
C
La, la la la la...

     Em                                   C
They say: "A guy won't get the girl, if he's not filthy rich!" 
G                  
It seems to me that's so heavy, 
     D                  
And weighs you down like lead 
       Em
Don't wanna be someone I hate 
C
that don't make no sense... 

    G
The sky is the limit 
       D
And I just wanna flow

Free as a spirit on a journey of hope 
G                    D
Cut the strings and let me go 
      Em             C
I'm weightless, I'm weightless 
(Ready, set, baby let's go)... 

    G
The sky is the limit 
       D
And I just wanna flow 
Em                      C
Free as a spirit on a journey of hope 
G                   D
Cut the strings and let me go 
     Em              C
I'm weightless, I'm weightless 
G                            D
Millions of balloons heading to the ground 
Em                           C
Weight of the world tries to hold us down

Oh yeah, (oh yeah), oh yeah, (oh yeah), oh yeah, (oh yeah), I'm free as a spirit 
   G                    D                                      Em
Oh yeah, (oh yeah), oh yeah, (oh yeah) There's nothing holding me down 
C 
Nothing holding me down
