KIDZ BOP was founded by Craig Balsam and Cliff Chenfeld in 2001. Each had three kids, Junk says, and while on the birthday party circuit, they started to notice a lack of music for school-aged kids.

In fact, according to Billboard, “In 2013, the franchise’s albums accounted for 18.8% of all children’s music sales.” The KIDZ BOP Kids perform more than 60 live shows in the U.S. each year.
