Pop music has been filled with utopias, but few sound more fun than Nellyville, a hip-hop candy mountain where reparations take the form of "40 acres and a pool." Nelly is mayor, of course, and he fills this LP with the sort of joyous, hook-heavy rap you'd expect to hear in such a village. "Hot in Herre" bounces on a shimmering Neptunes beat that feels as dynamic and liquid as the flows on top of it, while "Air Force Ones" cruises on stomping, slimy synths.
