2. “I’m on One,” DJ Khaled Feat. Drake, Rick Ross and Lil Wayne
2011's three hottest MCs unite, and the result is even bigger than the sum of its parts. Drake brings Ross and Weezy to his universe, where over-the-top balling and cold-as-ice emotion collide over a muffled, nocturnal bounce. This song ruled 2011, spending 11 weeks atop Billboard's Hip-Hop/R&B charts. And more than any other song on this list, it seemed to foreshadow hip-hop's future direction, at least for 2012. Not quite on one for our list, but pretty darn close.
