My unprofessional personal take on a few things being discussed on thread.
Although I always lower my head to hear of a personally preferred radio format to be flipped away, I can see Audacy having some programming on the HD2 version, as they do on 94.7 HD2 with country. My take is that it's the first step to possibly increasing interest in HD Radio. Still, it has to compete with alternate options, including streaming the same stations via company apps. Still I approve of doing so more than just making HD2 a Zombie Jukebox for fans of the old format.
With the limited growth of the KNX brand on FM in LA, I question if the coming 92.3 WINS will grow, or if it's more about sustaining an otherwise declining AM listenership. If it's the latter, I see this as putting duct tape on a hole in a boat. It might lower the leak, but without a longterm fix, it will eventually sink.
Country as a brand of music is popular in cities that aren't as predominant in a population of first generation immigrants. As for who listens to country, I see it as two camps. First are the people who live in rural areas. When you go into the suburbs, I identify it as 30 to 40 somethings who all listened to 90s Gansta Rap, when they were in Middle and High School. Just my observation of the population of the little microcosm where I live. With the latter, I question how long until they flock to a different sound. With that group, my observation is that they tend to follow each other, over time, to new and different sounds. In other words, they tend to follow the crowd than have unique preferences. That's not to say that is of all country listeners. In fact, I view most country listeners as being lifetime avid fans. Just that the group of which I mention is a group that can lower the numbers, once they move on to something different in another 10 to 15 years.
