The soundtrack to Ice Cube's Friday is one of the best hip-hop movie soundtracks of all time, and Dr. Dre's "Keep Their Heads Ringin'" was its biggest hit. It's a textbook '90s Dre banger, all high-pitched, squelching synths over punishing low end, but the overzealous singing and stale lyrics on the chorus make this one a bit of a chore.
