Eminem dissed a lengthy list of rappers on his new album Kamikaze, including Cleveland MC Machine Gun Kelly. Now, MGK has fired back with his Eminem diss track “Rap Devil.” The title is a play on Em’s 2013 hit “Rap God,” and finds MGK sniping at Eminem for allegedly trying to sabotage his career and (in his view) being old and bitter about his place in the current rap landscape.
