Blocking definitively radio streaming sites

[cib28]

How can I block definitively radio streaming sites for all pc in my company?

Configuration: Wingate Enterprise 8.5.9.4883, PureSight for Wingate 8.5.7.4879.


Thanks

I have partially solved, setting the Open DNS "Home" server on wingate with the radio category blocked.
