Mike Posner is at the head of a new genre: frat-house R&B. Posner, 22, released two mixtapes while he was a Sigma Nu brother at Duke, and on his major-label debut, he's still at the kegger, beer goggles fogged up with resentments and grudges. In the smash single "Cooler Than Me," he whines about a girl who won't give him the time of day. In "Cheated," he sings, "Nobody told me I was dating a whore." Posner's raspy croon is thin but insinuating; the production is serviceably swank, full of big, club-friendly synth hooks. But does anyone, frat boys included, really want to spend time with this guy?

“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."
