yes,but most of us consider the child ballads as folk songs,[whatever Mike tries to suggest otherwise]and it is not just the process that determines that its the style[or did before this discussion started]its the style.
in the same way CW has a style,that doesnt mean country cant merge into folk,it can and there will always be crossover and grey areas
most people would consider Sheath and Knife and Scarborough Fair a folk song,because of the style.
