Bingo!! You made my point!!!!!!

What you are playing cannot be accurately described as "folk music".

When you said "traditional tunes", that can desribe a variety of instruments and cultures.   Someone who dislikes British Traditional music would be bored to tears with what you play.

This is the problem with labels!   Having a bin that says "folk music" does NOT tell me if what you are playing is something that I would like.   While we can argue about whether contemporary singer-songwriters belong under the umbrella.

Folk music = fruits and vegetables (sometimes in more ways than one!)
