Following “Take Back the Night,” Justin Timberlake is back for another round with “TKO,” the second single off The 20/20 Experience – 2 of 2. After teasing with Instagram videos throughout the day, he debuts the 7-minute song, produced by Timbaland.

“I’m out for the count/ Yeah girl, you knock me out/ It’s just a TKO,” sings JT.

The follow-up to the best-selling album of 2013 arrives Sept. 30 featuring appearances from Drake (“Cabaret”) and Jay Z (“Murder”).

“The songs that I released in March just reminded me of summertime a little bit more and the songs that are coming out this month felt a little darker so they made me feel like the fall/winter collection,” Timberlake told Ryan Seacrest.

He is expected to debut some of the new tracks at this weekend’s iHeartRadio Music Festival in Las Vegas.
