This is 100% correct. I watched the acoustic performance Tal & Acacia posted on 
YouTube and these were the chords they used.

MERRY GO ROUND  by Tal & Acacia
Words and music by Acacia Walters-Wulfing
Capo 8

G
I'm on the merry go round of life
        G                        D
I wanna get off but I don't know how
      D               C
I can try to jump off right away, but
                         G
There's no guarantee I'd make it
G
Sitting on the same old horse
G                            D
Thought it was the prettiest yesterday
    D                   C
And now, I'm here going up and down
C (single strum)      D  (single strum) D
Never setting foot on real ground


CHORUS:
          Gm            Fm
I'm going round, up and down
          C             D      Gm     Fm    C    D
Round and round, up and over I go
          Gm            Fm
I'm going round, up and down
          C             D      Gm     Fm    C    D
Round and round, up and over I go
C
What do you do when you're stuck in a cycle
Gm
Over and over you go (you go)
C
"Never let go" they say, but I'm dizzy
D
Tired of the same old stuff


G
I'm on the merry go round of life
        G                      D
I wanna get off to fields wide open
   D                   C
To run and play on the waves of green
C (single strum)   D  (single strum)  D
Living beyond      these machines, instead...

(CHORUS)

C                                               Gm
What does it mean, what does if feel like to be free?
C                                                   D
Holding Your hand, living beyond what's in front of me
D
And what I see; no more...

(CHORUS)

And that's it! Pretty simple. Make sure you have it on Capo 8. That's what Tal uses.
