Is SoundMixer right for the job?

What I want to do is dynamically load from web an animation of mine that has music as it runs. Here it is.

This is an example of my work and loads if user clicks on a button. When they click to another page on the site the music still plays until the end of it’s duration. It looks really unprofessional.

Anyway I can target that loaded movieclip and get it to stop the music when not on the frame that displays that clip? (but still have sounds on the main site - buttons etc.)

I think I have to do some combination of checking frame, targeting loaded clip and perhaps a SoundMixer instruction? Please any help so grateful.

Here is my resume site that this all relates to. You will find the offending clip in the “web” section.
