Disc Jockeys (DJs), people who choose the music and link songs together for people to enjoy. You may have an image of someone spinning the CD or record on the turntable, but it isn’t that common anymore. DJs at dance halls or clubs usually use their PC to mix songs together now. DJs who use their PCs may use special software, if not pseudo-controllers that look like DJ sets to play the music. In that case, they no longer have to use turntables, once the main tool of DJs. Now that the music has been converted into data as well, it has become easier to move around from place to place. Today, we have a special feature on DJs, manipulators of music to liven up the atmosphere.
