Unlike most online radio stations, Radio Uproar's content is controlled by the members. When a member books air time, it's their responsibility to fill that hour+ with air time with content. Also unlike most online radio stations, Radio Uproar always live. What the on-air person broadcasts can be heard 10-130 seconds later (depending on internet/data speeds) by listeners. This means what is currently being aired is what you are listening to, you're not just posting a playlist on your page in hopes that people listen.
