I know media player tries to show a bunch of stations but unless you already know the station it's a crap-shoot at best. Then I remembered I used to check them using the YP. It's a list of the current Shoutcast streaming stations and what the play with all the details even something close to the current content...the URL is:

http://yp.shoutcast.com

I tried and it works perfectly. Browse to the site, click on the play button and viola Media Player fires up and you are streaming that station.

I am sure most folks already know about this but those who never used Winamp likely don't...
