If you can define music as something to listen to and enjoy, then I'm afraid a lot of traditional wailing of old men in those trousers that come up to your tits ain't folk music either.

Jim refers to collecting and cherishing a piece of the past. He collects songs, my mate collects beer mats. Jim calls his hobby folk music.

Many people love listening to songs being performed with just a guitar and, if the person is a good enough singer, unaccompanied songs. They call their musical enjoyment folk music too. On a good day, Irish diddly doo tunes get called folk music.

I used to own a company that made and sold vibrators. Our customers stuck them in wet concrete. Anne Summers sell vibrators. Their customers stick them elsewhere. Both are called vibrators, both operate on a similar principle. I don't recall getting precious about it.

Dictionaries have multiple meanings for the same word and nobody breaks a bottle over the other bloke's head for it.

Folk music is a broad church and I'm sorry but on this, Jim is wrong.
