I don't believe that there is any way that anyone could give more than a broad guess as to what the future will hold for traditional music. I was born in 1940 and the world has changed so much in that time that I doubt that my Grandfather or his brothers would recognize it now. I barely recognize it myself sometimes. It has changed in the last ten years in ways that I would not-could not- imagine in 1990. It will change in the next ten years in ways that we cannot even perceive today.The best that we can do is to continue to sing and spread the gospel. The songs that will stand the test of time will make themselves known by the fact that we, the singers and performers, will remember and sing them. The rest will fall by the wayside. It has always been this way.There are thousands of songs in archives around the world that no one sings because they lack that special quality that speaks to the soul. They are there. Someone wrote them. Someone collected them, but they no longer speak if indeed they ever did save for a brief moment.
The good stuff lasts, no matter what.
