Simple Flash issue adding sound to buttons

I need to add streaming mp3 functionality to the track buttons in the included fla. When each track button is clicked a different external mp3 file will stream to the user. When a new track is clicked the previous track will obviously stop so the tracks aren't layered. The sound off button will control all of the tracks and allow the user to stop the sound at any time. If you are able to add volume controls or track time monitoring please let me know. (not crucial, but added bonus) *with playback i've experienced a glassy metallic, horrible flash compressed sound- please include possible trouble shooting to keep this from happening if possible ## Deliverables the completed fla file w/ instructions for how to reference the external mp3 files ## Platform mac os x
