Problem with loadMovie reloading over and over

I created an external .swf that plays an mp3 and functions as a mute/unmute sound toggle. On its own it plays/toggles fine, but when I use loadMovie to load it into my main .swf it just starts reloading over and over until the song has started one after the next and it becomes a jumbled mess of overlapping songs.

I’m going to keep searching through the forums, but does anyone have any clues? I use loadMovie for an animated gif .swf in the same main .swf and that doesn’t give me any issues so I’m curious to know what my oversight is.
