Need advice on streaming for an event

Hi there,
Can anyone give me some advice. I'm hosting a party event, I've got someone to DJ, but how do I go about getting a stream to stream live music into the land? Is there some way of doing this without paying a lot for a relay stream? Not quite sure how it all works.

Any help appreciated !

Thanks

you can find streaming music here :
http://www.shoutcast.com/

and you can use a script like this to change land music with a voice command:
radio: url

//This simple script will listen for the owner to say radio: URL
//it will tune to the station specified by the radio: command.
default
{
     state_entry()
     {
          llListen(0,"",NULL_KEY,"");
     }
     listen(integer channel,string name,key id,string msg)
     {
          string lmsg=llToLower(msg);
          if("radio: "==llGetSubString(lmsg,0,6))
          {
               llSetParcelMusicURL(llGetSubString(msg,7,-1));
               llSay(0,"set station");
          }
     }
}

If you've got your own DJ, then try out http://qc1.net . They're hosting my station right now at $11/20 users/month. There are other hosts out there that might be cheaper, but I'm pretty happy with these guys because they haven't dropped my stream yet, and it's been almost a year.
