The genre of music that is sung rap.

Rap music, also sometimes known as hip-hop music, is a style of popular music believed to have its beginnings in African-American inner-city street culture. Rap musicians generally perform in a vocal style in which the lyrics are spoken, rather than sung. This type of music often deals with the hardships of inner-city life, though it is generally as varied in theme as any other style of music. Hip hop is generally characterized more by its often complex, rhyming lyrics than by its subject matter. Though it has its beginnings in the underground music scene of the 1970s, this music is today considered a very mainstream music genre, popular among people of all ages and backgrounds.
