How to stop audio layer playing in a separate scene?

Right- I have a music file dropped into a layer in my first scene. 2 scenes later, I want the music to stop. It would start playing in scene 1 and stop playing in scene 3. Currently the music has these settings:

When I press ctrl+enter, the music continues to play after the animation loops around again, and also starts playing again. So there's like two layers of music.

How do I make the music stop in a separate scene?
