"I spy with my little eye/Something that can get you high-high-high," M.I.A. declares over a belly-dance synth loop on this 2007 outtake. Is this a taste of the stalled LP her label is calling "too positive"? Here, too high is more like it. Pass summa that.

“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."
