Well, funny you should ask that...I was just going to post a tip on here about that problem. The solution is to click on the name of the station in the Shoutcast list to go to the station's own website. Then (usually) there are links to play the streams there -- however, you'll notice those links point directly to a .pls file hosted by the station. (For example, http://club997.com/CLUB977HI.pls) Those files generally don't move around. Use that URL instead of the one at shoutcast.com and you should be set.
