Dynamic background music based on your surroundings

The only application that I have seen that currently offers a free dynamic background music is the Opera GX browser that speeds up it's AI generated music based on what you're doing. The more I use it the better I concentrate and want to add it to my work environment and not least: Minecraft.

An AI that generates music that speeds up and becomes adventurous if attacked, beautiful and serene if alone and so on. 

I am aware Minecraft already customizes their music based on where you are, but to have a peaceful tune playing as you're fighting for your life isn't quite doing it for me esthetically.
