Comment:

While R&B and rap collaborations have conquered the charts in recent years, they're part of a peanut butter and jelly territory that's been treaded for decades. The production values may vary like the mixed frequencies of a radio dial, but there's no denying the gut-bursting soul linking Chaka Khan's quirky 1984 cover of Prince's "I Feel for You," the Kanye West-curated VIP room of "Slow Jamz," the piano-propelled gangsta stroll of "No Diggity," and the post-PlayStation pageantry of Usher's smash single "Yeah!"
