For the follow-up to his multiplatinum debut, “Jackpot,” Chingy has crafted “Powerballin’.” The set marks a turning point in the St. Louis MC’s young career. Having parted ways with Ludacris and his Disturbing Tha Peace clique, he now has to make a name for himself and his G.I.B. crew. Lead single “Balla Baby” is an affable attempt in that direction. Produced by Lil’ Mack, the song is driven by its infectious, sing-songy hook with Chingy’s Midwestern, twangy flow bouncing right along. His more R&B-influenced fare, whether teaming with Janet Jackson on “Don’t Worry” or R. Kelly on “Leave Wit Me,” is equally effective. However, the constant talk of expensive cars, gyrating women and endless parties quickly becomes redundant—and boring. Despite the few highlights, “Powerballin’ ” sounds all too familiar.—RH
