Light Em Up gives you, the people the power to determine what genre of music you hear next. Simply download the app and once installed select the color that corresponds with the genre of music you want played next. When you hear the boys announce "LIGHT EM UP", hold your phone up with your color lit. Whichever color dominates in the crowd dictates the sound. This is the first app of it's kind and will change the DJ game as we know it.
