Perhaps you could pre-mix everything but the music together and then average
that with your music. The music then would maintain it's constant dynamic
range and only your incidental sounds would be dynamically mixed together.

"Game Audio Programming" is one of the more dog-ear'ed books in my
programming bookcase. There are also many good sound articles in the Game
Programming Gems series from Charles River Media.

Also check out Csound, an open source sound library. An excellent book that
explains it well is "The Csound Book: Perspectives in Software Synthesis,
Sound Design, Signal Processing, and Programming" by Richard Boulanger
(Editor).
