It would be easy to apply restrictions on music.  We already give films, DVD's and games an age appropriate rating. In the United States, the Motion Picture Association of America is charged with the responsibility of providing ratings to consumers [1] .  It would seem that it would be simple to stretch these criteria to a similar music body. Therefore people would only be subjected to violent lyrics when it is deemed they are old enough to hear or buy this material, and it would stop younger people from being exposed to this kind of music. This also means that no new state-run institution needs to be created; it would operate, like the MPAA, independently of government control. As such, claims that any form of music censorship would suffer from practical problems are short-sighted, we simply need to extend the medium that already exists.
