Vikings had a complex democratic legal system, respected women, and had child rights. Furthermore, they practiced something very similar to rap battles.
Although these weren’t referred to as “rap battles,” but rather, flyting.

It provided great entertainment, especially during feasts, and served as a test of one’s cunning and intellect.
