Your mom and Eminem share the same references. He’s always a little bit (or a lot) behind the times, like your mother telling you about this cool new thing “Twitters,” which is how he ends up with references to Monica Lewinsky, Ray J, and planking in his unholy new song, “Rap God.” Em’s technical flow is outstanding, as rapid and twisting as ever; the lyrics and beat, not so much. “They said I rap like a robot, so call me Rapbot.” No.
