Am Sunshine;
FG There ain't a thing that you can do that's gonna ruin my night
(But there's just something about)
Am This dizzy dreamer and her bleeding little blue boy
FG Licking your fingers like you're done and
FG You've decided there is so much more than me. (Oh)
AmGF And baby honestly it's harder breathing next to you, I shake
G I brought a gun and as the preacher tried to stop me,
AmG Hold my heart it's beating for you anyway
AmEm What if I can't forget you? (Oh)
F I'll burn your name into my throat
G I'll be the fire that'll catch you
AmEm What's so good about picking up the pieces?
FGAm None of the colors ever light up anymore in this hole
F Oh
GAm Nobody prays for the heartless (No! )
F Nobody gives another penny for the selfish
G (You're learning how to taste what you kill now)
Am Don't mind me, I'm just reaching for your necklace
FG Talking to my mom about this little girl from Texas
AmEm What if I can't forget you? (Oh)
F I'll burn your name into my throat
G I'll be the fire that'll catch you
AmEm What's so good about picking up the pieces?
FGAm None of the colors ever light up anymore in this hole
Em Just give her back to me
FG You know I can't afford the medicine that feeds what I need
AmEm So baby what if I can't forget you? (What if I can't forget you?)
FGAmFG Collide invisible lips like a shadow on the wall and just throw, oh no
You can't just throw me away! (Am x12, Em x2) 
Am So what if I can't forget you?
EmF I'll burn your name into my throat
G I'll be the fire that'll catch you
AmEm What's so good about picking up the pieces?
G What if I don't even want to
AmEm What if I can't forget you? (Oh)
F I'll burn your name into my throat
G I'll be the fire that'll catch you
AmEm What's so good about picking up the pieces?
FGAm None of the colors ever light up anymore in this hole
Em Just give her back to me
FG You know I can't afford the medicine that feeds what I need
AmEm So baby what if I can't forget you? (What if I can't forget you?)
FG I'd better learn to live alone
AmF, G, End on 1 Am strum
