Check out Liquid Lounge, my music streamed direct from my server. It's random but invariably cool. At least, I think so.
You will need a player which can handle .pls files. Winamp, Media Monkey or even iTunes - if you must - should play the stream. There are other players.
I've included meta-data, so if your player is set up properly, you should be able to see song title and artist.
Hope you find it interesting.
