Girl Authority

That's right -- it's Kidz Bop for girls! Girlz Bop! Nine tweenies aged 8-13 take on the booty-shaking radio hits of the day (Gwen Stefani's "Hollaback Girl" and Rihanna's "Pon De Replay" among them) and dig back in time for grrl-power icons like Madonna and Pat Benatar. The nonet even provides its own censoring, using a series of vocal whoops to bleep out the objectionable words. You might argue kids are growing up too fast these days, but relax: the remake of "We Got the Beat" is pure, innocent fun.
