I listened for about five minutes last night on the way home. So that's---maybe 20 messages? There was one that I'd bet was local..."Nice to have 107-nine back. Looking forward to what you're gonna do." Everything else was so generic, it could have come from anywhere.
And, if you think about it---that's logical. This phase of the stunt was planned. So what happens if nobody's listening, or those who are don't use the "talkback" button on the app? So you have a library of these cuts ready to go (from other markets where you've stunted, custom-made for this stunt, whatever), and you sprinkle in any good ones you get.
