4: Billy Joel

It’s time to take a close look at Christie Brinkley’s ex-husband William. You may know him better as Billy. Billy Joel. It's Billy Joel. See, just because music is uncool doesn’t mean it can’t be good. Billy Joel is one of the most profoundly uncool pop singers of all time, but we both love him. We love his hits. We love his piano playing. We love his dumb music videos. We even love his early, pre-fame bands, The Hassles and Attila. Don’t know them? You’re about to.
