I'm using jplayer on my website but I have only one player on top which plays each mp3 on the page (like deezer). That's why I'm using demo04, as I want to display the current song playing and I want to add mp3 on the fly (maybe is it possible in an other way?). I can add music to the player with a simple link, for example :
<a href="http://www.jplayer.org/audio/mp3/Miaow-05-The-separation.mp3" class="track">The Separation</a>
So my problem is coming from the demo which doesn't prevent downloading tracks (right click>save target as) and I need this functionality.
In a few words, is it possible to hide the href or crypt it?
No this is not possible.
You can encrypt the name, but an encryption always has a decryption.
Also if you look at search result of Google you will find:
