You my try a general strategy of making small "song files" on the fly and passing them to whatever system you use. I guess the system would just need to be able to queue up a song ahead of time and play it immediately when the currently playing song ends. If the songs are something like one measure each, you could vary the score enough (on a nice beginning-of-the-measure boundary) to match the game mood as it changes.
If you record your songs into loops (little WAV files for a measure or two or four each, that seamlessly fit to the next section), you could actually play them simultaneously during a change in mood and cross-fade them by volume change.
Just some random thoughts... hope it sparks something for you.
