The rap, taken from verbal culture, which tied up with respective country\'s verbal tradition and created local version, became universal youth culture beyond one of the black. While the rap and hip hop became popular all over the world, Korea saw successful case to smoothly localize the rap and hip hop in its own cultural context. The success of the rap in Korea can be attributed to resemblance with Korean traditional rhythm and verbal culture. Having reviewed the origin of the rap and how it was accepted in Korea results in seeing contradictory nature of popular music of which imported culture is blended with own cultural tradition.
