Originating as a B side to their cover of the Stax classic “Tramp,” Cheryl “Salt” James, Sandi “Pepa” Denton and Dee Dee “DJ Spinderella” Roper came up with the goods on this career-making, Grammy-nominated platinum single about working it on the dancefloor. “Push It” has been sampled and spliced to death since it debuted in 1987, yet the original track is as fresh and fly as when SNP — among the few original women of hip-hop — debuted it. “Most men will never believe ‘Push It’ was never about sex,” said James. “And that’s why the record went to Number One,” said Denton. “Everybody thought it was about sex.”
