>>>>>>Nobody writes contemporary FOLK songs they write contemporary songs that they hope will be commercially successful -"<<<<<<<

That is absolute piffle! I know hundreds of contemporary folksong writers who write for a great variety of reasons, love of the music, trying to get a message across, political beliefs, to enhance local and national heritage etc. etc. If their songs are taken up by others or put out on a CD the commercial aspect is simply an add-on. Some of these are brilliant writers and their songs will stand the test of time.
For most of them the greatest accolade is having their songs sung by others.
