If you know the access details to the shoutcast server you should be able to use any player/ Listing service that supports shoutcast.
Your stream should be available via http://
<Shoutcast-ip-or-hostname>:<Port>/listen.pls for direct playback and a shoutcast statistics page should be available under this kind of URL: http://
If you need a web based player for your station you gotta go and find one yourself. Look for "shoutcast flash player" or "webradio player" in a search engine of your preference.
In case you don't know the IP and Port but only your spacial login details you should ask the spacialnet customer service.
Analog for CheapestStream customers.
There are only a few people around here that use the Spacial streaming service and even less people have the very new bundled versions of SAM Broadcaster (Plus / Lite).
So provide as much information as possible in order for us to help you.
