Imaginary Hot Topic is hiring you to be in charge of music that celebrates the history of their music department. Whether you make a playlist or decide to DJ the thing yourself is up to you, Imaginary Hot Topic Corporate isn't micro-managing this event. Play all the music, artists, labels you've bought or discovered because of Hot Topic's Music Department (except the ones not allowed by Twitch DJ rules, please look it up to be certain). You have time to dig up and rip your old CDs for this.
We prefer no more than two hours unless you're going overnight, West Coast time (slots 15-22).
