Problem with my preloader and attachSound

I have a very hefty SWF and I don’t want to load all of it before it plays. So, I put a framesloaded/totalframes and just put what I didn’t want to preload immediately after frame 100 (which happens to be music). The problem is that now, I can’t seem to access the music I loaded in frame 100 back in frame 70. Music I have loaded before frame 70 have no problem. Is there a way to bypass this without having to use external SWFs?

Thanks a bunch.
