Types of DJs
There are several types of DJs. A radio DJ plays music files (like mp3) or recorded CDs on a radio station and announces the names of the songs. A club DJ plays music files or recorded CDs over a PA system (an amplifier and loudspeakers) at a nightclub, rave, or disco. A hip hop DJ uses turntables and vinyl records to do scratching and make music while other hip hop musicians do rapping (rhythmic type of singing). Reggae DJs play recordings of rhythm instruments and then rap or "toast" (made-up chanting and boasting) with a microphone.
