Not pissing in KQK's cornflakes at all as I like the station, but PPM can give a lot of false info. If you go into a bar and KQK (or any other station) is playing, PPM credits whatever station it hears, even though you may be more interested in the conversation you're having with Barbie while trying to get her home and not listening to the station at all. Or if you're riding in someone else's car and they're playing their favorite station which you don't even have on your car radio preset button, they get credit for you listening. PPM is not the greatest audience measurement tool ever conceived. It's a very dumb device in terms of accuracy.
I see your point but I have a different view. If I was a business owner and I wanted to advertise on the radio, I would want the station with the most exposure. I wouldn't care one way or another how the listener got the message. If I was at the bar and Barbie got up to use the restroom, I might hear the advertisement and I might remember it. Same goes if you hear the commercial in someone else's car.
Though, I also see where it may affect stations that specialize in a target demo that your product only sells well with.
I still think the majority of the PPM numbers would still be the station of the meter's choice, generally. Though there are exceptions, it's still a much more effective way than relying on people to fill out the diaries.
