"I'm involved in the music business," crows Pitbull on his sixth album. That's both an understatement and a credo. Since his 2004 debut single, "Culo," the Miami MC has made good business of music, turning out records with a ruthless devotion to formula. Planet Pit plays a bit like a business plan. There are guest spots by R&B stars (Chris Brown) and Latin lovers (Enrique Iglesias). There are baldfaced rewrites of the Black Eyed Peas' "I Gotta Feeling" ("Give Me Everything") and Eminem's "Love the Way You Lie" ("Castle Made of Sand"). But there's something charming about Pitbull's enthusiasm - he sounds most like himself when he's promoting his brand. In "Give Me Everything," he uses his song to advertise his billboards: "Me not working hard?/Yeah, right, picture that with a Kodak/Or better yet, go to Times Square/Take a picture of me with a Kodak.

“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."
