BTW let me say I'm not criticizing the station in the OP, nor do I have anything negative to say about Hippie Radio. These are both options available to people who choose to listen to them. My comments are about people who then take those examples, and use them to suggest it could be popular if commercial classic hits stations in major markets did it. The facts demonstrate otherwise. The stations mentioned are not attracting the kinds of numbers that typical classic hits stations around the country are getting. I also stand by my comments that playing 50 year old songs, no matter how obscure, is not breaking up the monotony. These are songs that the people who love them should either own in their personal collection, or have them saved on the personal device of their choice. That's what they would have done when they were played originally, and it works just as well today.
As I pointed out, the station in the OP is an HD2 of a non-commercial station. It would not work well on a commercial station that depends on large audiences measured by PPM. There are lots of other non-commercial stations that do this around the country. There are a lot of people who have started LPFMs doing this. And that's all great and appropriate. But extrapolating anything else from it is ignoring the facts.
I used to argue with folks like Mr. Big A and Mr. Eduardo that there was a place for this kind of radio on the commercial frequencies. But after years of paying attention to what people listen to, and the music they care about, I've concluded that they are right. Most people really DO want to hear their favorite top 30 or 40 hit singles over and over.
I was a baby-boomer who grew up on Top 40 AM radio - then I got an FM/AM stereo radio from my parents for high school graduation. The FM "underground" stations (KPPC, KMET) were just getting started in my first year of college. I was totally enthralled by it. But really, that "golden" age of album rock only lasted a couple of years. By 1971, "Rock N'Stereo" KLOS started to dominate the ratings. No matter what people may think of KLOS in the 80s and beyond, in 1971 they were really
fake album rock radio - playing mostly Top 40 hits with a few album cuts thrown in. The DJs talked like FM jocks of that era (softly and slowly), and there were no jingles or loud Top 40 type formatting. DJ talk was severely limited. Just back-announce the previous song-set, read the weather, and go to commercials.
The point is, KLOS dominated the ratings by mostly repeating the same hits over and over - just like KHJ or KRLA, but that's apparently what listeners wanted to hear, because it kicked a** in the ratings. IIRC, ratings came back strongly some years later, but that was primarily with a much tighter format and strict playlists.
These days, with so many choices - MP3 downloads, Spotify, Pandora...there is even less of a place for this kind of programming on commercial radio. And really, I couldn't care less - I can build my own playlists of songs without spending much money, so music "radio" is becoming mostly irrelevant in my world.
