The 100 Best Songs of 2007

21 "Crank That"
Soulja Boy
A young Atlanta rhymer-producer cooks up a skeletal stomper and a no-budge MySpace clip, and ends up ruling hip-hop (at least for a few weeks).

22 "Keep the Car Running"
Arcade Fire
Over a mandolin riff, a propulsive two-step beat and a group-sung chorus, Win Butler murmurs and howls about the need to get the fuck out of a bad place. The best Bruce Springsteen song of 2007 not written by Bruce Springsteen.

23 "Teenage Love Affair"
Alicia Keys
This sunny head-bopper is an old-fashioned R&B make-out song, never getting past second base. But that doesn't mean it isn't full of erotic heat when Keys whispers, "Hey, boy, you know I really like being with you/Just hanging out is fine."

24 "What Goes Around . . . Comes Around"
Justin Timberlake
Timberlake's karmic payback tale is powered by a killer Bollywood-meets-Hollywood beat. "I was ready to give you my name. . . . Now it's all just a shame" — anger never sounded so sexy.
