I think CD's will be valuable-in part because while a source like itunes has a lot of music, including folk music, there will be rarities that will never surface on there. Which means that if you really are searching for a rarity to play in the digital medium, its going to have to come from cd. And it was just a short time ago-3 years or so when I worked in a record store that people were quite happy tracking down an import routinely priced at $60 for French rapper MC Solar. We would get one in, and it would be sold right away. That's more a question of what's hot I think, but if someone really wants something, they will pay.
