I am tring to stop sites like dizzler.com and such from hotlinking to the music files in my stored directories of my websites. They are killing my bandwith. I tried changing the .htaccess file and that didnt stop them, I tring using the hotlink protection in cpanel to stop them and that didnt work either. Any suggestions?????

You can do this easily in your host cpanel

You should ensure that all sites that you wish to allow direct links from are in the list box by going to the cpanel--> hotlink protection then this will bring you to the page you need where you can add your sites you want to prevent hotlinking.
