Apart from a slightly shameless plug of iHeart, it demonstrates to me that if an audience demands something, it's got to be delivered. I don't entirely endorse that because while music is a product, news is a service, obtained and packaged by trained people.
I weather random criticism, and many mixed messages about our coverage and choice of content, but I believe people would be appalled if we swayed to the whims of who was shouting the loudest. That way lies the potential to be nudged by interest groups, or even government.
Sometimes, when faced with the apps that allow you to design radio stations based around Neil Diamond, a news medium that you exert no control over, but serves an audience equally and as best it can, is refreshing. I open a paper, and there it is. Radio music may be evolving, and I enjoy the changes coming to news delivery, but like Neil Diamond, I still want the familiar, reliable sound.
