Some raps have flow. Some have the lyrical content. Some just have that hook that your cant get out of your head. A good rap song needs ALL of these. Add in dramatic piano stabs with an incredible Justice-esque synth and you have a GREAT song. Childish Gambino’s single Heartbeat is a true sign of the times: electronic music is reaching its sweaty fingers of influence into all genres of music. Childish new album CAMP is full of hipster credibility. The comedian/writer/actor/rapper has brilliantly witty, conscious, and downright dirty lyrics. I love it.
