Like a version of Now That's What I Call Music overrun by children, the unstoppable Kidz Bop series features youngsters singing pop hits while backed by adult musicians and vocalists. On Kidz Bop, Vol. 8 the kids get particularly rambunctious on U2's surging "Vertigo" and, oddly enough, Franz Ferdinand's post-punk single "Take Me Out," which features enthusiastic shouting at random intervals. For other tracks, the Kidz Bop crew mellows out a bit, most notably on the Frankie J slow jam "Obsession (No Es Amor)" and Gwen Stefani's shuffling "Rich Girl," while Avril Lavigne's "Nobody's Home" allows the ensemble to take on a sad yet soaring power ballad. For those who thought that the Kidz Bop collections were a passing fad, 2005's Kidz Bop, Vol.8 shows that these pint-sized vocalists have serious staying power.
