Music is a tricky issue.
I personally like it, though I've never been one to bring the music myself-it's something I never think of.But when others have it I enjoy it, if nothing else I find out how narrow and frozen in time my taste is, occasionally certain genres don't click with me, bit I can't say I would use the word offensive.
When playing in a group with music I am always amazed how clear the quality is within a group, yet 50 yards away not audible most of the time.
We allow it on the course, on the range only with personal headsets as it's likely you will have company who may not share your opinion or genre.
Occasionally, I have to draw the line between music that is simply too loud and intervene, or someone who is going out of their way to have a bug up their arse to complain about hearing any music on the course.Wind and holes which intertwine in a routing can compound this equation.
This makes my job a bit more difficult and I occasionally have to remind both parties of our policy of tolerance, but also but of not interfering upon the enjoyment of others. The two can co-exist with a reasonable volume and/or an occasional well timed volume adjustment just to be sure when approaching less isolated areas of the course.
Clearly others have different opinions on this board, and for those who go so far as to find an allowance or lack of anything offensive, it is up to them to seek out facilities that best suit their preferences, or when visiting a facility with a different policy to embrace the moment to enjoy something different.
I for one would never choose a facility based on its music policy, but I find the facilities I tend to choose for other reasons, almost always have a music friendly, but use common sense policy.
I'm a bit bemused to find out a course didn't make the list due to an ill timed musical blast, but then it's not my list.
