DJ Full Form is Disc Jockey. A Disc Jockey represents anyone who plays music recordings as his or her career. The role of a DJ might vary depending on which venue the person is setting up the music. For instance, a DJ could also work with a radio station to play the selection of music from a given playlist provided by the management. A DJ may also take the role of organizing a musical evening at a wedding and be in charge of playing the selection chosen by the couple and others.
Most often, a DJ is expected to interact with the audience and entertain them by making them dance for a number or announcing the event highlights and cheer the crowd. At times a DJ also takes charge of playing music in a club or bar. But unlike wedding events, here, he or she takes charge of mixing tracks of popular songs and best beats for the situation.
