Justin Timberlake's "TKO"

NO MORE TEASING: Justin Timberlake, who’s been popping up all over the place of late—including promos for the movie Runner Runner and a bizarre Vegas-set skit with Matt Lauer on The Today Show—has a new single in play after teasing it yesterday on Instagram. On the seven-minute “TKO,” the second track to appear in advance of The 20/20 Experience 2 of 2 (being serviced to radio Monday), “Timbaland’s beat of heavy drums and scratchy studio effects is reminiscent of a slightly more refined Justified”—at least that’s how Consequence of Sound describes it. Take a listen and see whether you agree. So where else will JT turn up between now and the 9/30 release date. For starters, you just might spot him at the iHeartRadio Fest in Sin City tomorrow night, and on Hollywood Blvd. hanging with Jimmy Kimmel Tuesday evening. (9/20a)
