what song types does flash play?
i know flash canplay mp3s. anything else?
You can only dynamically load mp3’s but you can import .wav’s and another file type, passes my mind right now. Try looking in your Flash documentation 
.mov sound-only files work, aiff with quicktime should be ok too…
best to import wav (not compressed) as you’ll export to mp3 compression, = loss of quality), if you’re not loading the songs in…
