Just to make a contemporary analogy - in the UK at the moment there is a discussion about changing the 'first past the post' voting system
Now, if I had to vote for just one form of music it may be 'traditional' folk but I'd much rather vote for many of the genres I enjoy in order of preference

The thing about traditional music and song is that it has time for all the 'turkeys' to be forgotten whereas some of the modern singer/songwriter compositions have still to face the test of time - a cruel test indeed and some will be found wanting.

The one thing I think can be said without contradiction is that music will never die - it may be transmuted, it may evolve into forms that are a long way from what pleased my generation or those of my forebears, it may be commercialised until it squeaks in protest and then return to the 'hearth' again but it will survive!

There are many songwriters out there; some are more 'unsung' than others some write so much from the heart that that is where it remains like the 'blossom on the desert air'

If you love a song - really feel a resonance - just get out there and sing it whatever meaningless category you put it in.
I was brought up in a singing tradition where folks just sang and didn't make these argumentative distinctions
