DJ Khaled is a one-man circus. He got his start as the preening ringmaster of Miami hip-hop radio before parlaying that renown into a recording career that brought the genre's biggest names under his ever-expanding tent. From taut club bangers like “I'm On One” (featuring Lil Wayne, Drake, and Rick Ross) to the kaleidoscopic trap slurp of “I Got the Keys” (with JAY Z and Future), Khaled creates tracks that are purely and sometimes maddeningly addictive.
