It's a movie about a super secret place in Africa, how about going African all the way?
If it's have to be music that the general audience can get into get it from somewhere in Africa.

When i see Wakanda on screen i want to feel like im there. I dont want to hear stuff i hear on the weekends blaring from cars.
