There are more factors involved that simply satisfying the target audience.
Here we go with the eyeroll comments.
Of course that was at a time when the audience had no other options other than their own personal music collections. That's not the case today. What we see often in today's alternative audience is a lack of tolerance towards any music they don't like. That didn't exist 30 years ago.
That doesn't seem to have stopped WXPN from making huge gains in the market. Maybe it's not a lack of tolerance toward the music, but rather a lack of interest in the way corporate radio ruins it.
The reason WRFF is putting a local host in mid-days is specifically to serve the local audience. There likely aren't enough listeners in other dayparts to support a full local staff. That's because those potential listeners are in their own personal music silos, listening to their favorite bands non-stop.
Please stop.
