Someone leaked 16 seconds of the new Justin Timberlake single, "Sexy Back," which is due to be released July 7 as the lead song from his FutureSex/LoveSounds. Like, this isn't even a PromoSquad snippet. It's not even a hook. It's just 16 seconds of Timbo-produced track, so trying to reconstruct what the song sounds like is sorta out there with reconstructing dinosaurs from their toe bones. Download if you must (we did), but rest assured: we have no shame, and will be jumping all over this the second the full track surfaces.
