How to control music background?

[bncl]

I have created a promo with two scenes, each scene has its own music background, and i have created a button on each of the scene for viewer to flip back and forth between two scenes, and here the problem is, when i click a button to goto to another scene, the music on the previous one keeps playing, so then i have two different music playing at the same time, how am i be able to confine a music to play only when it's scene is active? How do I stop one music from playing while the other one start to play?

Can anyone give me some help? Many thanks.

I think i have got the answer now, i just changed the Sync setting from "Start" to "Stream", and the problem solved, thanks for anyone who had thought of helping.
