Go to the Hoodstream streams page. If there isn't one 'on air', join the chat and ask if someone can PM you a link. There's not much in the way of intelligent music discussion, but plenty of cool people who will gladly share the wealth. I usually do the official webcast. But if money's tight, this is how I get my linkage and it has never failed (although the streams aren't always reliable and often seem to crap out during the jam of the night).
