1954 it was the date the ~1954 the International Folk Music Council defined folk music as "the product of a musical tradition that has been evolved through the process of oral transmission" but makes no firm statement regarding what is not "a traditional song cut off point" there isn't one!

traditional songs keep being found and published from collectors, made years ago some before and after 1954 ~few people recognise 1954 or even know about
