will definitely be writing about the dichotomy between folk and Folk!

I think Spleen Cringe nailed that one back here. Quote:

"Folk music can either mean 1954 definition folk music (which describes - imperfectly or otherwise - a process not a type of music); or it can mean folk club music/folk scene music - a context not a type of music; or it can mean what the general public/media/music industry think of as folk music (everything from Waterson Carthy to the Corrs to KT Tunstall to James Bl*nt to a metal band with a bit of acoustic guitar) - a marketing concept not a type of music. ... The one thing that unites the three variants on 'folk music' above is that none of them describe a genre/type/style of music - they are all simply convenient shorthand for describing something else."
