Louvin Brothers, "Knoxville Girl"
One of the creepiest songs ever, this is what a traditional Appalachian murder ballad sounds like being retold by an angelic brother duo. It starts innocently enough, with some guy by chance meeting a nice girl in Knoxville. By the second verse, things get dark: He beats her to death, throws her body in the river, comes home with bloodied clothes, has a nightmare, wakes up surrounded by the townspeople and is left to rot for life in a prison cell — all in the span of four minutes. While this song would even be taboo by today's standards, keep in mind that the Louvins' version of the track came out in 1956.
