Playing SHOUTcast in Windows Media Player

Windows Media Player can play SHOUTcast streams without any additional software. You can save the PLS file, get a stream URL from it, and then "File -> Open URL..." (Ctrl+U) in WMP. To automate the process, install Open PLS in WMP. Then it's possible to click on a "Tune In!" button and automatically start playing the station. WMP can even show song names!
