That's my point. Even the real fans don't listen all the time. They have the CD's and MP3s in their collections already. I'm sure some people are tuning in a few times a week or even daily, but are they listening to the SAC's for 4 hours a day every day? My hunch is that there are only a handful that do that.I don't listen to SAC most of the time, but from time to time I do enjoy AC/DC Radio.
