K-pop, or Korean pop (music), is a music genre from South Korea that consists of a mix of different music styles, such as hip-hop and pop music. In addition, K-pop is also a subculture.

K-pop groups are often a boy band or girl band. When such a K-pop group releases new work, it is referred to as a comeback, even when the artists or bands have never stopped and so there is no question of a comeback in the traditional sense. This is typical of K-pop.
