Things move on. These things will die if you let them. As Cultures change, their cultural artifacts, including music and song, change too. I think this is a good thing, so long as we continue to make music -any kind of music - let some of it be consigned to the museums. We are obsessed with preserving the past, let things evolve organically. As long as I can access the Louis Armstrong Hot Fives and Sevens in recorded form, let things roll, I say.
