Da Brat is like the Pink of hip-hop: aggro, punky, antisexy. But while Pink suggests tortured depths, Brat’s a one-trick tomboy. Here, she tries to expand into lovebird territory (”In Love Wit Chu”), but she’s too brash to pull it off. She is fabulously evil as a housewrecker on ”Boom,” but threats elsewhere ring hollow. Despite some impressive double-time rhymes (”World Premiere”), good lines are rare, and her staccato clatter grates.
