I can only agree with you- quite an achievement to get 'folk music' on TV, but the original question still applies. I love the older music amd song(although not all of it!) which is logical at my age although come to think of it, I'd be hard pushed to distinguish between the great old Irish ceili bands- eg the old Kilfenora or the Tulla, wonderful though they were.
So what's new? There's some awful rubbish about, but there always was- trouble is it all gets recorded & blasted out on dozens of 'platforms' these days. You just need to find what YOU like, and not just accept what some suited plonker in TV production puts in front of you.
