I love you, baby, but not like I love my guitar, Prince leers in"Guitar," between blasts of heroically pointless Edge-style soloing.It's his most slamming summer jam since "P Control" in the summer of'94, or "Alphabet St." in the summer of '88, or maybe "Delirious" in thesummer of '83. What did people do for fun in the summer before Prince? Planet Earth is one of those albums he makes when he's trying a littleharder than usual, if not hard enough to alienate his core audience,which loves him for indulging himself. "Planet Earth" and "Lion ofJudah" continue the hard-rock groove, while "Future Baby Mama" and"Somewhere Here on Earth" revisit his smooth R&B side. As for "Guitar,"he's decided to jack the post-punk revival, so he swipes a guitar rifffrom U2 ("I Will Follow") and a bass line from Duran Duran (the samesong that provides his album title). Wily bastard.

“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."
