How to show the loading % when preloading a sound?

Hello folks,

After searching on the forum, I didn't noticed a post about the subject:

• It's possible to show the loading percentage of an sound?

I want show the loading percentage of the first music to the player, because it will be sync with the animation on the future (after we completely redraw this frankenstein using an original music).
