Orwell depicted the ultimate totalitarian state. To speak of things Orwellian only implies that a particular action may be the first step on the slippery slope towards that type of society, not that we are anywhere close to it. If you do not believe the slippery slope is real just look at the amount of regulatory interference we accept in our daily lives that would have been unthinkable a generation or 2 previous. To me things like government threatening unspecified regulatory action against an industry is no different than a made guy coming into my place of business to sell me "protection".
Indeed Orwell did - I can give credit to the "slippery slope" concept employed here, and I can agree with your application of it in principle. Of course, the title of this thread is "Welcome to...," not, "We're heading towards," thus my objection. What is proposed in the press release is not censorship, however, I agree that such labeling could then lead to censorship - i.e. you have catagorized the literature by gradations and may then institute censorial guidelines by those catagories.
However, I really don't think such a destination is likely to be in our future. Americans are more than willing to allow their civil liberties to be trampled, given that it either does not inconvenience them or that it increases their convenience. (The suspension of some civil liberties would/does/will result in safer, more stable communities, and that's all most people care about.) While many parents are more than willing to encourage censorship (many great literary works are still banned from high school reading lists/libraries) to "safe guard" their children, I just am not convinced that broad scale censorship of popular music would fly.
In truth, there are few people who are sincerely and totally opposed to censorship, regardless of their rhetoric. Viewpoint discrimination is a way of life in our country. Conservative schools disparage liberal writers and/or ban their books. Liberal schools disparage conservative writers and/or ban their material. The difference is perspective, not principle.
