I've started using a product called SAM2 from spacialaudio.com for the feeder. Runs on NT, so I have to stream from my cable conneciton to my server. Nice thing is you can add a great playlist feature and even a "request mode". Although I lost the ability to dynamically change the playlist; the Request feature has been very popular. Trade offs, I suppose.
I change the voting to send me a notification when to drop a song from the list. And I download new tunes into the playlist on a regular basis.
Its been one of the more popular additions to our site. Even talking to JJMcKay about doing a station ID for us! lol
