Anyone know how to stream music using in-game voice chat?

I hope this isn't something wrong or what not, but I'd just love to play something like when next I'm at the head of a small fleet of aircraft ready to swoop down on the enemy, for all to hear

Anyone have any idea how to do this though? I tried setting my sound card to default playback in Sound, but that doesn't seem to have done the trick, as the test shows that nothing was heard. Also when I play it through my mic I hear it sounds like a 'broken speaker', so I am striving to be able to do better :|

I've heard people do this sort of thing before - do you guys have any idea how to do it?
