Verse:
C
Stop this runaway car
      F
I wanna get off

I wanna go back
       Am                                    G
If I left you there then I left it all behind
C                                   F        
Cause all I’m feeling now is the weight of the world bearing down
    Am                                           G
I don’t have answers to any of my questions anymore

Chorus:
                           C
'Cause I might have been wrong
                   G
I might have been scared all along
                   Am                          G
I might have been standing on the top of the world
                     C
What a difference a day makes
               G
I turned and watched you walk away
                     Am                            G
I might have been standing on the top of the world
                              C
'Cause I might have been wrong

Same for rest of song, ends on C
