Whilst there is a lot to be said for the more trad folk music, as with trad jazz, there is room for progression. I'm sure that in years to come there will be comments about the 'classic' songs from the 60's, 70's, 80's, etc., you know' they don't write them like that anymore'.Time moves on and everything will progress accordingly and some people will prefer one type to another.A bit like a bottle of wine!
