The soundtrack to John Singleton's road-racing film features 15 rap anthems, most of them new and all of them perfectly primed -- like the movie itself -- for a rap/rock/club marketing trifecta. Most are crossover-heavy and tending toward Southern bounce, led by co-star Ludacris and his Disturbing tha Peace posse; both I-20 and Shawnna get feature tracks, as well as heavy plugs inside for their upcoming Def Jam South full-lengths. Star Tyrese gets a track with Ludacris and R. Kelly, but it's weaker even than his solo work for J Records. Joe Budden's immense left-field hit "Pump It Up" is the highlight here, followed by Trick Daddy's "Represent" and Ludacris' own "Act a Fool."
