Judging by your earlier comments (e.g. Extraordinary … a folk forum in which there are people more worried about the age of the performers rather than how good they are at their craft.) I don't accept that you are being as objective as you last post tries to suggest.

You used the term "pop" in a concious way to put these artists down. It's a pretty damning indictment on a forum such as Mudcat. They clearly do not sing or play pop music by any categorisation that the majority of people would understand.

Have you never sung a modern song or added musical accompaniment to your singing? (It's OK, I know the answer is yes to both).
