From: Kendrick Lamar "Keisha's Song" (2011)

Who they were: "Keisha's Song" definitely wasn't recorded for the Disney-Channel tweens set. It told the tale of Keisha, a 17-year-old prostitute who got killed by a man after being raped. But at the end of the song, Kendrick revealed that he let his 11-year-old sister listen to it shortly after he recorded it to show her the dangers of prostitution and to try to steer her clear of becoming the next Keisha. Powerful stuff.

Where are they now? Dead. We hope Kendrick's little sister was paying attention.
