May I respectfully suggest that you become am member of WXPN? I've just renewed my membership.
XPN is a listener-supported radio station from the University of Pennsylvania. It's the home of The World Cafe. It's a great place to learn about music beyond the pablum on the regular radio stations.
It's my favorite radio station and I don't live -- or work -- in range of its broadcast. Thank goodness for the web and broadband.
I would point out though, that I've been a member since before I could regularly listen on-line.
So. Maybe you should become a member and support the station too!
