I think one of the oddities and discussion points is what do you do if some song has a killer sing a long chorus, but the lyrics are in this case at odds with the happy go lucky Mariachi pastiche music? It is relevant to folk music, in that a folk song is one taken up by the people, often these days spreading virally at sporting matches with very strange choices taking off. Ok it started off as a hyped up story, and much ado about nothing for clickbait. However, some of the principles involved are an interesting side line.. and Mudcat is a discussion group.   I also re-iterate that the lyrics in question were at least part written by a woman.. although the male in her life took credit for the lyrics.. which was music business and marital misogyny.
