Groove Over Dose, known by the acronym g.o.d, is a South Korean boy band formed by SidusHQ. Debuting in 1999, the group became one of the most popular boy bands of the early 2000s in South Korea. The members had gone on to solo careers in the entertainment industry after indefinitely discontinuing group activity in 2005 following the departure of a member. However, they regrouped as a quintet and made a comeback in July 2014. Although the group is largely known for their "story telling" lyrical style and signature blend of R&B and rap, their repertoire features a diverse array of genres ranging from hip hop to funk.

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.
