It’s finally going to happen, people. Many songs enter, but only one jam can be crowned the Song of the Summer. Guy, Oliver, Margaret, and Wynter bring their picks and some suggestions from the Facebook group and discuss what really makes a summer jam. Writer and analyst Chris Molanphy comes in with hard data to see what is objectively the Song of the Summer. Sia, Calvin Harris, DNCE, Lizzo, and so many more are brought into the fight. Who wins? The answer may shock you.
