After teasing the new track with several videos and photos, Justin Timberlake has finally debuted "TKO". The new single follows up "Take Back the Night", the lead cut off his forthcoming "The 20/20 Experience - 2 of 2" album.
Produced by pal Timbaland, the seven-minute track features Timberlake singing about a girl from his past. Thinking he's got over his former flame, he feels something different when seeing her with another man.
Featuring guest vocals from Drake and Jay-Z, the second installment of Timberlake's "The 20/20 Experience" is scheduled to arrive on September 30.
In an interview on Ryan Seacrest's radio show, Timberlake explained that he wrote so many tracks for "The 20/20 Experience". Instead of scrapping some songs, he decided to release them all in two separate albums.
"I just felt like so much of it went together. I wanted to release a double album, but then after speaking to my label, we thought it would an interesting idea to see what it would be like to split up a double album and release it over the course of a year," he said.
"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," he added.
Timberlake is expected to debut some new "The 20/20 Experience - 2 of 2" tracks when he takes the stage at iHeartRadio Festival in Las Vegas on Saturday, September 21.
