I wont lie: I say a daily prayer (or seven) asking the music gods for new Justin Timberlake music. They must have heard my prayers (PRAISE) because we got to see Justin flex his musical muscles on his appearance last night on “Late Night With Jimmy Fallon.” It’s not a new album or anything, but the result was almost equally as awesome.

As a follow-up to their incredible “The History Of Rap,” Justin and Fallon (Jallon?) dropped their fiery sequel aptly titled, “The History Of Rap Part 2.” Though it was clearly just an act, while being interviewed by Fallon, a seemingly coy Justin was reluctant to even think about attempting to top “Part 1″: “No, no, no, stop. It’s not gonna happen.” said Justin. “We can’t do it again, we can’t top–” And then JT intentionally gazed over to Jimmy and reached behind him to grab a mic… Game on, folks.

Backed by The Roots, Justin and Jimmy voyaged down rap’s memory lane (part 2): Salt-n-Pepa‘s “Push It,” Vanilla Ice‘s “Ice Ice Baby,” DMX‘s “Party Up,” and (my personal favorite) Nelly‘s “Hot in Herre” all made an appearance. And in between a little Cali Swag District and 50 Cent, the duo seamlessly transitioned into Lil Wayne‘s “A Milli” just before closing out their set with Biz Markie‘s “Just A Friend.”

I’m not sure why it takes a late-night show to get Justin Timberlake to hum a few bars, but I think we’d all like to extend a collective “THANKS!!” to Jimmy Fallon for facilitating even the tiniest hum from Justin’s previously on-strike vocal chords.
