This is hilarious. It’s from the upcoming Raaaaaaaandy (Aziz Ansari) COMEDY mixtape. Basically, in this song he yells at a bunch of rappers who “promised to send him verses” but never did…including Kid Cudi, Jay-Z, Ludacris, Drake, RZA & GZA, Dr. Dre, Eminem, Clipse, MF DOOM, Mos Def, and Kanye West. Check it out.
