The secret lise in the two names out songs are recognised by. "folk" and "traditional" - two sides of the same coin.
"Folk" refers to the social group that probably made them, identified with them, and took ownership of them as being 'local' or Norfolk' or 'family' songs

Nope ~folk song and music continues and does include the traditional~ but is being written and continues to expand and evolve ~ contemporary folk song ~ including industrial song and songs of social comment ~ you stick to your ideas Sir but the word is still very much in daily use and is properly used ~and yes I agree you can tell what is a folk song just by hearing it ~ pop or popular song and music is just that! and sod the folk programme guys
