13. "SARAH" BY KATE MILLER-HEIDKE
I honestly almost didn't include this one, because it's just on the verge of TOO disturbing. It's based on something that actually happened (although it's a fictionalized account) and it talks about a girl being abducted from a music festival. It never reveals what actually happened after she disappeared, and that makes it so much worse. But the story combined with Miller-Heidke's ethereal vocals and the music make the entire thing beautiful and upsetting at the same time.
"Oh Sarah, I didn't mean to let you down
But you left me on my own, Sarah
Why didn't you scream? Why didn't you shout?"
