Along with the expected teen pop fare from Britney Spears, Christina Aguilera, Hilary Duff, and Kelly Clarkson, Kidz Bop included more left-of-center picks like Franz Ferdinand's "Do You Want To?" and Modest Mouse's "Float On" as the series evolved. Along with the regular Kidz Bop collections, which were released roughly twice a year, the franchise expanded to include DVDs and collections of oldies, Christmas songs, and Latin pop hits. Kidz Bop also developed ring tones, toys, and a clothing line over the next few years. The Kidz Bop, Vol. 11 album, which featured a cover of Gnarls Barkley's "Crazy" as well as renditions of songs by Justin Timberlake and JoJo, emerged in 2007. Other releases that year included Kidz Bop, Vol. 12 and Coolest Kidz Bop Christmas Ever.
The series continued releasing albums every few months for the rest of the decade. By the time of 2011's Kidz Bop, Vol. 20, the series emphasized the personalities of the Kidz Bop Kids, which included Steffan, Eva, Elijah, Hannah and Charisma. The success of subsequent volumes like Kidz Bop, Vol. 22 and Kidz Bop, Vol. 23 -- released in 2012 and 2013, respectively -- continued the project's winning streak, which included over 20 albums that debuted in the Billboard Top Ten, regular number ones on the Billboard Kid Albums chart, and many gold certifications. The 2010s also saw a Kidz Bop satellite radio station and a regular live touring company led by Ashlynn, Bredia, Grant, and Matt. ~ Heather Phares, Rovi
