Cumbia Rap is a fairly new spin off of the original cumbia genre. It consists of a more traditional Columbian rhythm, as well as some hip hop and reggae type additions. There are many pioneers of cumbia rap which include Tropa Estrella, and Chicos de Barrio from Coahuila, Mexico; as well as the Kumbia Kings from Texas.
Cumbia is the net intersection of three cultures that settled in Colombia at different times: indigenous peoples, Spanish/Moorish and African slaves.
Cumbia is very popular in all of South America (except Brazil), as well as Central America and Mexico (see Mexican cumbia).
In Argentina, for example, this social divide is exemplified by the cumbia villera phenomenon, that intends to represent and resonate with the poor and marginalized dwellers of villas miseria (shanty towns and slums), with lyrics glorifying theft and drug abuse.
