Thanks, Calum. The URL (address) for the Podcast feed is:

http://www.afolksongaday.com/podcast/podcast_feed.xml

On Winamp, you should find a selection titled "Podcast Directory" on the left-hand side of your screen under "media library." Copy-paste or type the feed URL into the "Add Feed" box at the bottom of the page, and click the "Add Feed" button. I think most media players can be set to automatically download podcasts. I confess that this is the first time I've tried it - it's very easy to do.
