Mac Miller has won a lot of people over, roughly as many as he had in the first place. The Pittsburgh rapper was too young when he first got rich and famous. Credit is due; he tried. He seemed genuinely interested in hip-hop, a teenager who liked A Tribe Called Quest and Big L. But his music, while invigoratingly youthful at its best, was glaringly juvenile at worst. “You was Easy Mac with the cheesy raps,” jabbed battle rapper Loaded Lux during an interlude on Mac’s sophomore album, Watching Movies with the Sound Off. While it’s true he “killed the game like Jeffrey Dahmer did the ‘80s” (as he puts it on his new album’s Juicy J-featuring “Break the Law”), it didn’t exactly garner him lasting respect from the rap world at large.
