I think some 'folk' just don't LIKE extra categories....and they want everything they 'like' to fit neatly under one category.

Sure...there are nice, interesting songs written every day about subjects of concern to the 'folk'.....but we have had a name for those for a long time. They are topical songs. If they are good, popular topical songs, they may in time be passed on in ways that eventually qualify them as folk/trad.

This doesn't mean we 'folk' singers can't sing them yet....it just means they are not sorted and absorbed yet. Some of Woodie Guthrie's
songs got 'absorbed' pretty fast...as have Ewan MacColl's. But writing a song protesting about Iraq does not automatically qualify it as folk/trad.

No one is judging 'quality' per se...just noting that some songs are listed in certain categories for convenience and relevance.
