I listen to a number of folk radio programs over the Internet.

At the moment (Friday morning 10:30 EDT), I'm listening to a nice folk show from Maine with Chris Darling at www.wmpg.org.

My favorite folk show is Folk Roots/Folk Branches with Mike Regenstreif on Thursday mornings from 9-noon at www.ckutfolk.com.

I also really like the Midnight Special with Rich Warren. It's live on Saturday night but is archived for listening all week at www.midnightspecial.org.com.
