Old Space Countdown

I'm making a music pack and I want to put the Old Space Countdown back in the game for when I'm in space during ERZ1 & 2. I have an ogg file for it and when I tested in the tunes. It worked but it doesn't play automatically when I'm in space. Is it possible to make this happen? If so, HOW?

You could probably make it play with a lua script. Just use it to check if your in space and then tell it to play the music.

But, this would enable cheats and you'd only hear it for five seconds and it'd be constantly interrupting the normal level music. It's too much work for too little of reward.
