Pill Popping Jukebox is a term used to describe DJ's who only play other peoples songs. They will tend to dance around playing with controls on the deck
in front of them as if they are contributing somehow to the music.
PPJ's often feel empowered by the fact that people are dancing to the music being played while they are behind the deck
When infact most people in clubs will dance to anything that is played, often dancing to sound checks.
