That link doesn't work - I use Shoutcasr server on my Threads site:
http://www.viperalley.com/shoutcast/index.php?compact=0
with mostly customized stuff that reads the data from the server. I even made a little voting script that lets people votes on the songs being played and links to the Request page (I run SAM2 as the feeder).
Shoutcase will give you an XML response that you can parse using a XML parser like scxml-obj.php
