Hip hop has spawned dozens of sub-genres which incorporate a domineering style of music production or rapping, and it exhibits elements of trifunctionalism.

Hip-Hop has now expanded and gone on a global scale, millions of rap albums are sold in foreign countries, some are not English speaking countries, yet people go out of their way and purchase these albums even thought they don’t understand the message the song carries, and manage to memorize the lyrics and sing along not knowing what they are saying. In foreign countries Hip-Hop has influenced natives to pursue rap careers and do what is being done in the United States such as following the trends, in their country. This is a product of globalization and it explains how popular culture can be interwoven with the everyday life of individuals that follow it, and how it can affect them in many ways.

Like jazz, hip-hop is one of the few musical genres that scholars see as entirely American. Here, it is important to note the varying social influences that affect hip-hop's message in different nations. Frequently a musical response to political and/or social injustices, the face of hip-hop varies greatly from nation to nation.

For example, 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 has become much more than just music, it has evolved into a lifestyle, encompassing all aspects of life including language and fashion. The music of Kwaito is both politically and party driven. The politically fuelled music gives a voice to oppressed people that have no other way to voice their concerns and find music to be very accessible, not only to themselves but also to the audiences they are trying to reach. On the other hand the club driven music can also be seen as political in the sense that the artists couldn't care less about the post apartheid life they live and are more concerned about having a good time and not how their access to this life came about. Kwaito is a music that came from a once hated and oppressed people, but it is now sweeping the nation. The main consumers of Kwaito are adolescents and half of the South African population is under 21. Some of the large Kwaito artists have sold over 100,000 albums, and in an industry where 25,000 albums sold is considered a gold record, those are impressive numbers. In the end Kwaito gives aspirations to the oppressed people of a post apartheid South Africa, where they now have a control over a very influence source of media, music.

In Jamaica the sounds of hip hop are derived from American and Jamaican influences. Jamaican hip hop is defined both through dancehall and Reggae music. Jamaican Kool Herc brought the sound systems, technology, and techniques of Reggae music to New York during the 1970s. Jamaican hip hop artists often rap in both Brooklyn and Jamaican accents. Jamaican hip hop subject matter is often influenced by outside and internal forces. Outside forces such as the bling-bling era of today's modern hip hop and internal influences coming from the use of anti colonialism and marijuana or "Ganja" references which Rastafarians believe bring them closer to God.

Author Wayne Marshall argues that "Hip hop, as with any number of African-American cultural forms before it, offers a range of compelling and contradictory significations to Jamaican artist and audiences. From "modern blackness" to foreign mind", transnational cosmopolitanism to militant pan-Africanism, radical remixology to outright mimicry, hip-hop in Jamaica embodies the myriad ways that Jamaicans embrace, reject, and incorporate foreign yet familiar forms."
