After discussing with the few people who were on today, I've tentatively set up an IceCast for us to play themely/mood music while playing the game.
ATM it can support 25 listeners which should serve pretty much anyone who wants to listen since at best SD hovers around that many players at once anyway.
You can connect to the server with the following players using the links:
Windows Media Player: http://sc1.phx.icastcenter.com/tunein.php/koztah/playlist.asx
Real Player: http://sc1.phx.icastcenter.com/tunein.php/koztah/playlist.ram
There is also a web player and request widget here:
I'm going to keep it up for a month or two to gauge interest. If no one's into it I'll take it down. If you all enjoy and connect to it I'll leave it up.
