Hip-hop music originated among the Black American during the 1970s, with a deep influence from the Jamaican music. Hip-hop employs bass as the main instrument and includes rapping and audio mixing. Bob Marley and Roberts Nesta Marley were the pioneers in popularizing hip-hop music. By 2000, hip-hop made its way to the world music charts, and now with the success of hip-hop artists like Eminem, 50 Cents, Usher and Akon, hip-hop is going places around the globe.
