Creating an Script to serve mp3's to a flash player, but not elsewhere

[gcarn]

Im not sure if this is possible, but I'm trying to make a music player on the site, that keeps the source mp3 files secure from regular downloading.

This player needs to read its playlist from an XML sheet.

Ive been streaming the files to the player via a serveFile.php?fileID=5 kind of script, but I can not find a way to test if the page serveFile.php is being hit from someone typing it into the browser (and they get prompted to save serveFile.php, even though it is the mp3), or being accessed through the flash player.

I think I've tried everything I can think of.

Any thought's or approaches anyone else has taken to secure the files from direct downloading, would be appreciated.

Just realize that if somebody wants the music, they can get it. Even the best music players aren't 100% perfect.

Well, I completly realize that the content its always stealable.

My goal was to make it not so simple to enter the url thats in the playlist and get the mp3.
