On the trio's first recording since 2004, the punchiest female R&B group of its generation - specialists in aggressive inspiration - exercises impressive restraint; "Nuclear" is a billowy love song, with gentle harmony vocals wafting over a Pharrell beat that winks back at early-Nineties hip-hop soul.

“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."
