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?

“Everyday People”

"Everyday People" managed to trailblaze in two different ways -- it was one of the first pop hits to deal with the subject of racial harmony, and it utilized Larry Graham's "slap" technique on the bass guitar, which would soon be copied by countless other bassists. Graham once said about his pulsating style, "I'd never done that before … that's where the freedom of creativity came in for the band, that we'd be allowed to do that." In 1978, the song's line "Different strokes for different folks" would be borrowed for the title of the hit television show Diff'rent Strokes.
