Background Music Demo

Hi, Jackson, 

Is it possible to have the background music play across layers, if I wanted to add interactivity in the middle of the video?

I'm creating an animation that has the same audio continue across multiple layers on a single slide. I want to add a button feature on one of the slides without interrupting the animation on these layers. At the same time, I want the button to take the user to a certain layer. Is this question clear? 

I'd really appreciate your help. 

Thanks,

Lubna.
