1. Jay-Z f/ Rihanna and Kanye West "Run This Town" (2009)
Album: The Blueprint 3
Producer: Kanye West, No I.D.
It's arguable that Rihanna, Jay-Z, and Kanye West are the three most influential musicians of our day, and "Run This Town" found all of them on the same track at the same damn time. The song delivered: reliable bars from Hov, the requisite perfectly written Rihanna chorus, and a scene-stealing, extra long guest verse from 'Ye. The success of the track quieted any doubt over the third entry in Jay's Blueprint series. Incorporating so many elements of the current zeitgeist in one place, "Run This Town" will ultimately go down as a finer example of rap music in the modern era.
