Before he became the top dog on American Idol, Randy Jackson was a musician-producer who worked with everyone from Whitney Houston and Bruce Springsteen to Madonna. On his eclectic solo debut, he continues to play well with others, including Mariah Carey, Joss Stone and fellow Idol judge Paula Abdul, who kicks it J.Lo-style on "Dance Like There's No Tomorrow." Jackson also uses his Idol connections on "Real Love," with Elliott Yamin and Katharine McPhee making like Marvin and Tammi. Best is "Home," a twangy take on Michael Bublé's hit with the unlikely pair of Anthony Hamilton and Big & Rich's John Rich. Not every collaboration works, though: Jackson fails when he tries to go gangsta with Crunk Squad and Ghostface Killah on "Like A."
