Exercising none of the production restraint that made Usher's "Climax" spring's best quiet-storm jam, Diplo achieves awesomeness the opposite way on this six-song set. He throws synthesizer tantrums full of chest-beating bass lines and calls in pottymouthed MCs like Nicky Da B, who helped turn "Express Yourself" into a NSFW YouTube classic.

“Tonight's the Night”

The lead cut and title track from this girl group's debut album, "Tonight's the Night" was written by 19-year-old bandmember Shirley Owens, who sings lead, and producer Luther Dixon. The band from Passaic, New Jersey met in high school, first calling themselves the Pequellos. The song's frank thoughts about sexual and emotional surrender was racy for the time, but that didn't stop the Chiffons from cutting a similar version immediately after the original came out. "We were the first female group to write some of our own material," band member Beverly Lee recalls. "We did have some say-so in our writing."
