Britney Spears Greatest Hits: My Prerogative,'' limited edition with bonus CD: You may not approve of Britney Spears' personal antics, but you can't help but shake your thang on the dance floor when her songs come over the club speakers. This compilation tracks her growth from a flirting teenager in ``. . . Baby One More Time'' to a woman who's not afraid of baring most everything in ``I'm a Slave 4 U.'' It also includes her latest single, a remake of Bobby Brown's ``My Prerogative.''
