The classical music definition above makes kind of sense in that it recognises that even within the classical tradition the meaning of 'classical music' has more than one meaning. One more encompassing meaning and one more specific meaning.

It would make sense for a folk/traditional definition to likewise point out that there are different meanings. Even looking at it from a specifically Scottish perspective it seems clear that even though we know what the 1954 definition specifically means there is a significant canon of Scottish tunes and songs that the vast bulk of performers and listeners would regard as folk music but doesn't neatly fit into the said definition. Not really talking about pop music as much as generally composed fiddle tunes and composed songs from Burns' day up until modern times.

So yes I can say that I listen to classical music and know what I mean by that - and then I also know that Mozart is of the more specific classical period whilst Mahler is not! I live with that quite easily. Likewise I also know what is meant by a specifically folk/traditional song/tune - but I also know that there is a much larger canon of work thought of as folk or traditional music. Words have more than one narrow specific definition. It seems rallying against that after half a century or so is kind of spitting into the wind.
