We've all heard an unsettling song or two, and sometimes, we realize that the lyrics aren't exactly fiction.
So, we'd like to know: What's a song you were shocked to learn is actually based on a true crime/murder? Maybe you loved to chill out and listen to "Suffer Little Children" by the Smiths until you learned it's actually inspired by the grisly Moors Murders committed by Ian Brady and Myra Hindley.
Or maybe you were shocked to learn that Kurt Cobain actually wrote "Polly" about the real-life kidnapping and torture of a 14-year-old girl in Tacoma, Washington in 1987.
Whatever it is, share it in the comments below! Tell us the songs you were shocked to learn are actually based on a true crime, and feel free to give a little detail about the case. We'll feature your responses in an upcoming BuzzFeed Community post.
