Justin Timberlake performs another song "Let the Groove In" from his upcoming release The 20/20 Experience set to be released March 19th, 2013 in his third apparence this week on The Late Night Show with Jimmy Fallon. Timberlake backed by The Roots and a woodwind and brass section let his funky side out. The album will be Timberlake's first release since his last chart topper FutureSex/LoveSounds in 2006. This single offers insight into the various styles that Timberlake is venturing into. The title of the track is perfect, the song is groovy to the core, so much so that towards the end it is ended with an interlude of an Earth Wind & Fire classic, "Shining Star".
