Reduce volume of town music?

[CautiousChaos]

Hey folks,

I'm crawling through some of the wikis on Civ4 trying to find what XML node might be responsible for the playing of civilization-specific music when you are zoomed into a town.

I personally find it annoying, so I was going to reduce the volume down a bit. The closest thing I found is as follows, but it doesn't seem to work.

Is there a compendium somewhere of what these tags are for (even outside of the audio ones?)
