Why the 'Either/Or contruct', Sinister Supporter?

Not so much Either/Or as Subject/Object, which is a curious dichotomy in itself when it comes to humans studying other humans. Otherwise, I was simply asking a question; if a song is removed from the natural habitat that defined it as a folk song in the first place, is it still a folk song when those criteria (i.e. those of the MCMLIV Shibboleth) are no longer being met? Interesting to note that Garfinkel first came up with Ethnomethodology in 1954 as well...
