Hip hop music has spawned dozens of subgenres which incorporate hip hop music production approaches, such as sampling, creating beats, or rapping. The diversification process stems from the appropriation of hip hop culture by other ethnic groups. There are many varying social influences that affect hip hop's message in different nations. It is frequently used as a musical response to perceived political and/or social injustices. In South Africa the largest form of hip hop is called Kwaito, which has had a growth similar to American hip hop. Kwaito is a direct reflection of a post apartheid South Africa and is a voice for the voiceless; a term that U.S. hip hop is often referred to. Kwaito is even perceived as a lifestyle, encompassing many aspects of life, including language and fashion.
