Lady Sovereign

The twenty-year-old British S-O-V, affectionately nicknamed by Def Jam president Shawn Carter, delivers her first U.S. single for rebellious young teens and unassuming hipsters. A disciple of message boards and grime-music offshoots, the self-proclaimed midget MC drops honest, childish lyrics (sans ghostwriter) over Casio keyboard riffs and "Planet Rock"-like drum patterns. The single is catchy, but take it for anything more and you've been brainwashed.
