It's been a while, but here I am posting a very simple test program.
If you have 2 background cues, say ambience and battle, you could switch between them with this code.
Keep in mind that LoopEvent = Infinite only in the ambience and battle cues not in the transitions to and from ones.
Here is the code. If you want the exe and resources let me know and I"ll post it somewhere is some 20MB with my music.
This is my Game1.cs file
Code:
