Amazon.comIt's not because of the irresistible banger that is "Kiss Kiss," and it's not because he's rounded up a guest roster that reaches across the hip-hop universe and pulls T-Pain, Big Boi, and Kanye into orbit: Exclusive solidifies Chris Brown's rise in modern R&B circles because it's a tight, stylish album that reeks of major-career potential. Yes, he's straddling the grown and sexy thing even though he's not yet out of his teens (see "With You," "You," and "I Wanna Be"), and yes, he's pulled in a lot of different directions by a lot of top-tier producers, Scott Storch, the Underdogs, and Will.i.am among them. But the thing that'll grab longtime R&B listeners about Exclusive is the way it hangs together--Brown can belt or go breezy with the best of them, and he doesn't strain for credulity even when faced with lyrics more suited to R. Kelly's wised-up vocal caliber (see "Take You Down"). Last go-round, on his debut, Brown was a hotshot. This time he's just hot. --Tammy La Gorce
