The big music publishers are beginning to see that offering individual downloadable tracks via music portals is a way of marketing their music., so why should not folk music publishers use this market as well? If Fellside, Greentrax, Green Linnet, Topic and whoever else developed a joint portal (or had it developed for them) where they could sell individual tracks from their catalogues, that wouldn't make the music free, but certainly a lot cheaper than buying a whole CD if all you're after are three tracks from it. Who's going to suggest it to them?
