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.
