LIVE MUSIC
I have a live shoutcast radio on my pc, which I regularly broadcast.
The address to it is http://80.222.213.226 . If that link works and you get onto a page, it means the server is online and I am also playing.

I don't play all the time because it's LIVE music. I play my synth pianos (Yamaha PSR-640 and Kurzweil PC3x), mostly improvisation, but sometimes some oldskool game music as well. The radio should work with the following players:
iTunes, Winamp, XMMS, VLC and Windows media player.

Just use a "open URL/Stream" option somewhere in the application.
If you wanna hear an example of how it sounds, you can visit my Youtube channel.
However, in my opinion I usually play better live. Also, the sound quality is much better in the Radio than in Youtube.
