Good timing. I've been listening to a few of the online radio stations at the link below. I was going to start a new thread, but it fits here nicely. Depending on your taste - The Roots, Handcrafted Radio, Planet Radio, and Route 66. Most of these are going to play deep cuts, not the usual limited playlist of classic rock.
