Well, it's pretty obvious what's going on here--the four people, who you probably know, in the photograph above are working on something together. I would assume it's a track set for Justin Timberlake's second installment of The 20/20 Experience that's dropping this fall since, you know, people of this caliber don't just hang out together for shits and giggles. That's just my theory, though.
As you can see, Timberlake was joined by Jay-Z, Nas and Timbaland in the studio at some point, and the collaboration to come is certain to be goliath. I really don't know what more to say, so, that's really it.
