Chingy proves that St. Louis is not a one-rapper town with his Capitol debut. The newly appointed member of Ludacris’ Disturbing Tha Peace camp shines on his major-label bow, “Jackpot.” Lead single “Right Thurr” has already established him as a red-hot hip-hop newcomer. With its catchy hook and feel-good party vibe, the single is a bona fide summer anthem and introduces a new dance, the Chickenhead, to the masses. Like “Right Thurr,” much of “Jackpot” is about pimping and partying. That said, Chingy and the Trak Starz, who produced the bulk of the set, find a way to make these trite topics vibrant and new, thanks to synthed-out tracks and Chingy’s easy-going drawl. Witness “Gettin’ It” and “Sample That Ass” (featuring Murphy Lee). With infectious songs to keep the party going through the rest of the summer and well into fall, Chingy’s “Jackpot” is a safe bet for any hip-hop fan.—RH
