I think this version is pretty easy to play and sounds almost like the original :)
Enjoy!
[Intro]    
Am   C    Am    C    (x2)
[Verse 1]
Am
Dark as midnight
C
Six pack Coors Light
Am                 C
You don’t look the same
Am
Past my bedtime
C
Blue and red lights
Am            C
Come take you away
[Pre-Chorus]
        G              Dm          F
Hate to see you like a monster so I run and hide
        G                  Dm       F
Hate to ask “but what’s it like to leave me behind ”
[Chorus]
Am         C          Dm
I won’t be no I won’t be like you
Am        C                 Dm
Fighting back I’m fighting back the truth
Am        C           Dm    F     
Eyes like yours can’t look away
        Am         C F
But you can’t stop DNA
        Am         C F
No you can’t stop DNA
[Verse 2]
Am
Twice a year
    C
you come in crashing
Am              C
Nice to see you too
Am
Johnny Cash
    C
and backseat laughing
Am              C
Always ends too soon
[Pre-Chorus]
        G                Dm          F 
Hate to say hello ‘cause I know that it means goodbye
        G                  Dm       F
Hate to ask “but what’s it like to leave me behind ”
[Chorus]
Am         C          Dm
I won’t be no I won’t be like you
Am        C                 Dm
Fighting back I’m fighting back the truth
Am        C           Dm    F     
Eyes like yours can’t look away
        Am         C F
But you can’t stop DNA
        Am         C F
No you can’t stop DNA
[Bridge]
        Am        F           Dm        Am
Are the pieces of you in the pieces of me
      C     F              Dm       Am
I’m just so scared you’re who I’ll be
     Am  F        Dm       Am
When I erupt just like you do
     C       F          Dm      Am
They look at me like I look at you
[Chorus]
Am         C          Dm
I won’t be no I won’t be like you
Am        C                 Dm
Fighting back I’m fighting back the truth
Am        C           Dm    F     
Eyes like yours can’t look away
        Am         C F
But you can’t stop DNA
        Am         C F
No you can’t stop DNA
[Outro]
