Question : How do I restrict users from listening to streaming music with Group Policy?

How do I restrict users from listening to streaming music with Group Policy?

I want to be able to restrict one of my user accounts from listening to or playing ANY streaming music from the Internet with Group Policy. I have created an OU with just that single user inside of it and I have created a "lock down" policy for that OU so ANY user that I place inside will adhere to this policy. Now, I want to restrict listening to ANY streaming music from the web with this policy. Any ideas WHERE to disale/enable this restriction within Group Policy?

Thanks,
Matt

Another option: Configure allowed\disallowed content type with your router\firewall. I configured very specific parameters using Policy Editor on  a Watchguard Firebox...
