HELP WITH FLASH MX .. Desperate

Does anyone out there know how to make a hyperlink to a button that allows the viewer of your flash movie able to downlaod a sound file.

That is I have music that I produce and I want to allow people to visit my flash site the ability to download the music file, but I don’t know how.

Can anyone out there help? I need an idiot’s guide to how, I’m a bit dim!!
