Download link in dynamix text field

hi

I have a .txt file with html code inside of it that loads into my swf. i’ve managed to create a link (ain’t i the genius) but the problem is that if the link ponits to another website e.g

a href=“http://www.something.com/file.mp3
it just opens the file in the browser.

is it possible to get it to download the file instead?
i’ve tried searching but i can’t find a answer.
