Virtual Tabletops and music

[Face_P0lluti0n]

I like to use background music in games, but I may be migrating from "meatspace" tabletop to online tabletop soon. Does anyone know of any software, virtual tabletop or otherwise, that would allow me to control and sync up the music playing on all of the player's computers? I'm worried that if I just use speakers in the background of my gaming space, it will sound grainy over skype/ventrilo/etc, and get in the way of my voice when GMing.

Thanks in advance for your help and information

EDIT: For the bonus round, if anybody knows any good, free voice-changers for my NPC voices, I would appreciate recommendations!

Thanks!

I would suggest getting Virtual Audio Cable if you use Windows. Or figure out how your audio cards/chipset "What you hear" driver does. What VAC(Virtual Audio Cable) does is create a seperate line in/out so you can play music on WinAmp/WMP/FooBar and dump it out to Ventrilo. In Ventrilo you setup a seperate user with a sensitivty where it recognizes when music is playing and cuts in. Then in Ventrilo you set up this user so that he overrides any other user. This way you don't get the five streams problem. I do this in my games and it works well for a quick get in the mood song then mute the player. As for playing background music constantly, my players and I find this more annoying than helpful.
