46. Salt-N-Pepa, "Push It"
Salt-N-Pepa's signature jam was one of the first rap records to top the dance charts, and it remains a classic party-starter. The electro groove is a monster, and the refrain distills the message of half the songs ever written in nine indelible words: "Push it! Push it good! Push it real good!" Cheryl "Salt" James and Sandra "Pepa" Denton weren't technical virtuosos, but they trounce all comers. "Back then, there weren't many women," Pepa recalled. "We were raw, we were bold, we were in your face with it. We did not care!"
