what I am prepared to discuss,if you provide the 1954 definition is how it can be applied to modern songs such as John Lennons,with the proviso that the 1954 definition[has flaws and is not perfect]but is the best definition that is not subjective.
This is Different from, What I expect to see,when I go to a Folkclub as a paying visitor[because thats my subjective feeling],which does not have to be logical but can be emotional.
An example of illogicality, but emotional gut feeling,is the use of Traditional music for toothpaste adverts.It could be argued that getting traditional music to people who have never heard it before must be agood thing,.
but in my opinion using it as an advert for toothpaste demeans it.
logically this argument can be defeated,but it still doesnt alter how I feel[subjective emotional],in the same way turning up to pay to see someone at a folk club is subjective[emotional],not necessarily logical.Dick Miles
