A disc jockey is a person who mixes different sources of recorded music for a live audience in a nightclub or dance club. Disc jockeys are also called DJs. DJs typically perform for a live audience in a nightclub or dance club or a TV, radio broadcast audience. DJs also create mixes, remixes, and tracks that are recorded for later sale and distribution. In hip hop music, DJs may create beats, using percussion breaks, basslines and other musical content sampled from pre-existing records. Disc jockeys play remixed versions of popular songs in the music industry.
