Do you have any experience with making movies?
If i was to give you a task, and i say: Create a promotional video (like a TRAILER), showing the best aspects of this simulator, and please make it a little dramatic, so it gives some impact.
Sound effects, i leave that up to you.
If you can do this without music, and keep me entertained, i will say no more. But hey, on the side, i'll make a movie as well, only WITH music, let's see which one people will enjoy most. ;)
Music is a part of movies, it's just how you use it that matters.
