Well songs about murder are already on the table so I've got a few of those. There's one I couldn't find, it's a hidden track on the end of one of Alison Moorer's albums. It's the true story of her parents' murder/suicide. One of the most haunting songs I've ever heard. The only hit I got was lyrics only, no audio. Song is called Cold, Cold Earth. Moorer is the sister of Shelby Lynne and one of Steve Earle's many ex-wives. She never really made it big in Nashville but is a talented singer/songwriter.
Anyway, back to songs I could find.
