Jimmy Fallon and Justin Timberlake are hilarious and so good. Justin Timberlake's face singing Lauren Hill's part in Killing Me Softly comes to mind. Their history of rap includes a good variety of songs from influential artists like Kurtis Blow, Salt n' Peppa, Beastie Boys, LL Cool J (YUM!) etc. I guarantee you will have to sing and dance with them, at least I did (to my hub's dismay). Make sure you watch the whole video to see parts 2 and 3 (it's worth it!). If you're interested in part one you can try here.
Confession: Due to my, uh, age and lack of juvenile influence, there are a few songs of which I've never heard. That's okay, though, because I know all the good stuff ;)
Confession: As much of a music snob as I can be, I do like Justin Timberlake. I consider him a guilty pleasure, kinda like chocolate.
I give props... So Hip Hop Hoorayyyy Oohhhh Ayyyy Ohhh...
