The 1990s saw the emergence of three distinct music genres: RAP, ska, and METAL. RAP is a genre of music that originated in the United States in the 1970s and is characterized by its use of rhyming lyrics and a rhythmic beat. Ska is a genre of music that originated in Jamaica in the late 1950s and is characterized by its upbeat tempo and distinctive offbeat guitar sound. METAL is a genre of music that originated in the United Kingdom in the late 1960s and is characterized by its aggressive sound and distorted guitars. All three genres have had a lasting impact on popular music and continue to be popular today.
