Best anti-leech script for hide url

i have web service people can embed mp3 song


but i dont want they know the real mp3 song


i need anti-leech script so mp3 url like this http://www.domain.com/mp3url.mp3 is masked like http://www.domain.com/redirect1.php


so people definitely cant see the real mp3 url, i have try some anti-leech script but i still can se the url


let me know link to anti-leech script that you believe the best you ever see

why not just use .htaccess to block access to it?

actually all mp3 song is outside my website, i just embed with the url

this is perfect example from mask url for embed object

can you search where is real mp3 url located?

i'm not really sure sorry.
there are some people here great with JS/PHP that might be able to help.

I think Javascript will helps you. Try posting this in the Javacscript forum.
