No one has embraced the Top 40 bootleg/mash-up craze more than Girl Talk. On their latest release, Unstoppable, R&B smutmonger Khia sings about her neck and her back over Richard Marx’s “Right Here Waiting,” and various clips and pops from perennial favorites like Snoop Dogg, Sean Paul, Jay-Z and P-Diddy are peppered throughout the disc. In a time when kids can barely sit through an entire album by just one artist (the horror!), this A.D.D. mix will keep them sedated and/or spastic.
