With just over a week until the sequel to his Billboard-topping, platinum-selling 'The 20/20 Experience' arrives, Justin Timberlake delivers the second single from his second album of the year.

After taking back the night with funky, dance floor moves on the previous offering, JT explores deeper emotions on 'TKO' as he describes the flooring feeling of seeing his ex-girl out with a new man. Timbaland's chirpy, hip-hop bounce echoes back to the pair's earlier work, way before the first '20/20 Experience.'

Featuring two sole appearances from Jay Z and Drake, 'The 20/20 Experience 2 of 2' releases Sept. 30. The album is available to pre-order on iTunes.
