[mx] Stupid Sound Looping Issues

Alright, so Macromedia says Flash can’t really loop mp3s seamlessly, and suggests importing WAV files. But if you’re using AS to load an external sound at runtime, this is not possible. So I ask you, coding geniuses, is there a work-around to the silence that Flash adds to the beginning (end?) of an mp3 file, thus causing it to loop incorrectly (I’ve already tried adding a decimal to the secondsOffset and it sounds awful).
Thanks in advance.
