Webradio, Internetmusic, how can I do it ?

Ok, I have ATV latest version. Firefox browser, NitoTV etc.
I want to play music that is available from http://www.arabella.at, Austrian wegpage. It is also available via shoutcast.com, when I search for that stream within firefox, but when I hit play, nothing happens. The shoutcast app in Boxee does not have this stream.

Any idea ?
Any other app that I can install and open with Nito that can handle these streams ?
