Sound files-exporting for actionscript

hey, i got this tutorial for making a simple music playing button. And the best thing was, it would export the chosen track for actioningscripting, via linkage. however i havent used flash for a while and when i do the samething again i can’t get the music file to compress in flash. Previously it took a track that was 4mb big and made it into a 200k…what am i not doing? can anyone help…can anyone understand my ramblings? yay/nay
