I was intrigued to read this:

With very few exceptions, radio music presenters are given playlists, from which they are not allowed to stray, containing all the latest manufactured groups and artists whom the recording companies want to promote and surprise, surprise, those playlists contain no folk music, nada, zip, zilch.

So if that is a fact, what does that say re: the oft-repeated lamentations here about various Unthanks, Rusbies and Lakepeople etc. "selling out"?
