If you are interested in listening to folk music online be sure to check out the other threads concerning the subject. Especially:
Update of Audio Folk Music on the Web Folk music all day on the Internet
or filter for as far back as you want to go on "Radio", "Real Audio" or "internet". With the "Radio" filter you get the added advantage of links to all of the Mudcat Radio threads.
As I have mentioned before in the last two years we have gone from having folk music on the web be a rare thing to having so many sites that it is difficult to separate out the good from the bad.
