Justin Timberlake makes a long-awaited return with the release of his pulsating new single, 'SexyBack,' from his second solo album, 'FutureSex/LoveSounds,' due Sept. 12.

The track opens with a stern assertion: "I'm bringing sexy back," Timberlake states in a voice so laden with effects it's almost unrecognizable. Enter hip-hop heavyweight Timbaland, who instructs ladies to  "Get your sexy on."

It's a hot, sweaty synth track. Girls, feel free to swoon. Boys, take notes. Everybody dance.
