The fat, squishy bass blasts on Britney's 2007 "Freakshow" were many listeners' first exposure to the sounds of dubstep, the U.K. style favoring syncopated beats and huge low-end. Now, M.I.A. producer Diplo has put together a dubstep party platter: His jam with Lil Jon ("U Don't Like Me") is positively unhinged, while U.K. producers Benga and Zomby represent for the style's experimental side. Elsewhere, Stenchman's remix of "Burn" by Australian Idol diva Jessica Mauboy posits how dubstep could rescue modern R&B from groove tedium.

“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."
