For the first single from a pop superstar's new album, the Timbaland-produced "SexyBack" is as odd as it gets – a thunderstorm of synth pulses underneath Timberlake vocals rendered alien by pitch-shifting, distortion and Lance Bass knows what else. But as Timbaland chimes in with a chant of "Get your sexy on," it's easier to accept the song – if not the transformation of "sexy" from adjective to noun.

This story is from the August 10th, 2006 issue of Rolling Stone.

“My President”

Young Jeezy teams up with Nas on this track, in which he compare his own success with the idea of an African-American winning the Democratic Party's nomination in the 2008 presidential election. "When I pulled up in my car, that s--- was unbelievable to people in my neighborhood because they were like, 'We grew up with him. How the hell did he accomplish this?'" he told Rolling Stone. "I feel like it was the same way with Obama. I grew up all this time, but I've never seen a black man this close to running this country."
