Chance the Rapper and Jeremih try to keep Christmas real by sweet singing about Jesus, then slipping in some rap about the troubles of the world–you should Christmas out those bad times for those put upon! Chance ends “Joy” with the shout-out: I’m on my 773 love, probably a reference to a Chicago phone code (made famous in the hit “Jeremih Loves 773” which also includes the other Chi-town area code 779).
