51. Y.C. f/ Future "Racks" (2011)
Producer: Sonny Digital
Album: Rack Nation
Label: Universal Republic
While it's never been determined whether or not Y.C. is actually speaking English on this song (seriously, does anyone know what he's saying?) that didn't stop the tune from becoming a major hit. It also introduced hip-hop at large to Future, who's obviously become quite popular in his own respect. The official remix for the song featured Young Jeezy, Wiz Khalifa, Waka Flocka Flame, Cyhi The Prynce, Bun B, B.o.B, Yo Gotti, Wale, Cory Gunz, Dose, Cory Mo, Nelly, Twista, Big Sean, Trae and Ace Hood. In other words, it was an entire mixtape on one song. But since then we haven't heard much from Y.C. himself.
