The Urban Artist: Alicia Keys
What She Brings to the Table: A Keys has a string of successful hits that gives her the resume necessary to tell others what they're doing right and wrong when they sing.
Why She'd Be A Great Judge on The X Factor: She may not be as assertive as Diddy—or Nicki, for that matter—would be, but don't get it twisted: Alicia Keys knows her stuff. She's also probably more musically proficient than any of the other urban acts on this list and could really translate that into a successful run as a judge. It'd help her own career to show off a little bit of her personality on the show as well.
