If I "splain" I'm afraid I'll spill the beans to some CBS lurker who'll spoil the party for her and probably a few others.
The fact is, I don't know for sure what she's using to listen. I have a pretty good hunch, and I could always ask her. I won't do that, but I'll go this far.....
She could be listening on her Mac book, but I doubt it. She's obviously not listening on her HD radio (won a few years back in a BBC contest). Nope....so that leaves her iPhone. I'm pretty sure that's it, but I'd rather not say which app I suspect it is. I've probably said too much already.
BTW, I agree 100% that advertisers....from Joe's Garage to whoever is dictating the local Pepsi-Cola buy....couldn't care less about their messages reaching statewide, nationwide, or worldwide. The problem is all the greedy individual interests thinking they're each entitled to a piece of the golden goose that they're killing. I agree that performance fees do need to be paid....but there has to be a fair and reasonable solution devised which includes a point where rights holders must say "when".
