K-pop, short for Korean popular music, is a form of popular music originating in South Korea as part of South Korean culture. It includes styles and genres from around the world, such as pop, hip hop, R&B, rock, jazz, gospel, reggae, electronic dance, folk, country, disco, and classical on top of its traditional Korean music roots. The term "K-pop" became popular in the 2000s, especially in the international context. The Korean term for domestic pop music is gayo, which is still widely used within South Korea. While "K-pop" can refer to all popular music or pop music from South Korea, it is colloquially often used in a narrower sense for any Korean music and artists associated with the entertainment and idol industry in the country, regardless of the genre.
