Wow!! This is super creative! Great presentation and the songs made me laugh! But my word they are a very fickle radio audience! You can lose that audience so fast it gives a sense of mild panic at all times! I feel empathy all of a sudden for radio show hosts!
Only critique would be the moment of silence. I went from 1500 audience to 0 in 3 seconds and was so confused when I lost. 2nd time I knew it was coming and still lost 3/4 of my audience to it just cause of the bit of transition into and out of the event status. The event itself is really funny and a great shakeup! I'd just recommend giving some more buffer to react on that one.
