Musical Scores in MA

One of the things that hits you when you play MA is the lack of music. The vast majority of maps have NO musical score of any kind. The few that do usually have just one at the mission entrance, which quickly fades out as you get deeper into the map.

So, what I'd like is the ability to choose from a dropdown a musical score, to be triggered by the following:
1) While reading the chapter introduction
2) While reading the chapter success/or failure text
3) Entering the mission
4) Selectable position on the map ( or Front/Middle/Back)
5) At a hostage location
6) At a defeat boss location
7) At a destroy object location
8) At a defend object location
9) When an ambush is triggered.
10) Mission completed.

There are already quite a few decent musical rifts present in the game. These should be made available, and more should be added over time - just as often as they do costume updates.
