19. Beyonce, "Crazy in Love" (2003)

There aren't too many love songs that can shift a dance party into overdrive.

"Crazy in Love," powered by a dangerously buoyant Chi-Lites sample, is capable of doing just that, and when you can get an entire dance floor moving to a song about how much you love your (eventual) husband, you know you've struck gold.
