Based on the lyrics of the rap, the audiences and the rapping industry as a whole, it is easy to show how rap can cause crime and discrimination in a society.Rap music, usually known as ârappingâ â also known as emceeing, MCing, spitting, or rhyming â refers to spoken or chanted rhyming lyrics (Wikipedia).hough people can argue that rap music has emerged from the negativities in the society, the impact of rap on the society itself is greater.
