There's something very interesting to be revealed how rap music migrated forwards and backwards between America's deep South and California's S . fransisco. Separated by the majority of a continent, Memphis and Oakland are an awful lot closer than the usual might think. K Check, Juicy J's newest artist-and Sage The Gemini's former manager-has dropped his new single, "On Me." It features not merely the Three 6ix Mafia lynchpin, and also Compton rapper Problem and Baton Rouge's favorite canine enthusiast, Kevin Gates. It's Gates who opens the song having a pretty, uh, vigorous character portrait of an certain woman.
