Many Minnesota clubs -- including mine -- are wrestling with the "music on the course" issue. There's not much middle ground: the noise crowd wants to know why the old farts are harshing their buzz, and the old farts want to know why you want noise on the golf course.
I do know that there are younger players who are voting with their feet and leaving clubs that don't approve of, or allow, music on the golf course. When it becomes a significant enough economic issue, be prepared to hear "Long Train Running" or "Smells Like Teen Spirit" in your backswing.
One of the things that's so puzzling about the golf business is that everyone talks about it as if everybody has to follow the same path.
I agree with what you've written about, and surely the solution should be that some clubs allow music, and others do not, and golfers can gravitate to the place they're happier with.
Unfortunately, it rarely works that way. Private club members are locked into one particular place which has to have a contentious yes or no vote about it; and daily fee operators tend to decide they can't give up any potential customer, so they will generally bow to whichever way the wind is blowing.
If clubs could cooperate better, they could just trade some of the members who like their peace and quiet over to the stodgy old course, in return for younger members.
And don't be so sure that there aren't any younger people that would prefer to keep the golf course quiet.
