Timbaland is nearing the release of the second installment in his "Shock Value" series, and from the sounds of the first single, "Morning After Dark," the producer is back in stride. Much like the material on his first set, the song heaves with massive sub-bass and weighty kick drums. "You talk about taking it slow/I'm talking about taking it wild/Don't wanna be too upfront, no/Baby you know it's my style," Timbaland flirtatiously harmonizes over a galactic-sounding, double-speed piano and thumping beats. "When the cats come out, the bats come out to play," he croons on the catchy hook, which features his new label signee, SoShy. While comparisons to the 2007 cut "Return the Favor" are undeniable-lacking shock value on that end-this club banger will send shockwaves through your speakers nonetheless. -Mariel Concepcion
