For Frontin', the first single off their upcoming compilation, platinum producers the Neptunes do their the-sparser-the-better, hit-or-miss melody thing over typical thumps. Singing silly lead, Pharrell does his tiresome, freaky falsetto thing for, presumably, the ladies. But then, surprisingly, guest rapper Jay-Z's smarmy-smooth, player-for-life thing segues into some seemingly heartfelt settle-down sentiment (Holla back, Beyoncé!). Guess sometimes things DO change.
