Ahahaha at Ouch's new name.
Super: a couple of quick points.
1. You've entirely missed the point that "regulating" music content to kids will have on the musicians' and producers' ability to publish such music. As Ouch! (or Mrs. SM; you two make a cute couple) pointed out, the labeling system on games makes a
de facto ban on certain "adult" content in games. It effectively limits what even
adults can buy. The same thing would happen to music all because you don't want kids hearing some naughty words.
2. I have no idea what you mean by "regulation." If you're referring to a voluntary sale-restriction like some stores have for M-rated games and some movie theaters have for R-rated movies, that's one thing. If you're talking about the government prohibiting the sale of certain content to minors (as Australia, that you referred to, does in some contexts), then that is illegal in the US (see
Brown v. EMA, ruling that a CA law banning the sale of violent video games to children was unconstitutional).
3. Considering that parents already have the authority to consent to sale of explicit content to minors, as well as to restrict what they're exposed to if it's legal, such regulation only places Puritanical values as a
substitute for parental authority. It places moral judgment on how parents should raise their kids and to what content they should allow their kids to be exposed to, and makes them take extra steps if they disapprove -- with no opt out option. It's not yours or anyone else's business. You have no basis to demand that everyone follow your own personal moral judgments about appropriate content.
EDIT: Also, SM, have you ever even been into a Hooters? It's a family sports' bar. If you could get over yourself for half a minute, you'd realize that the kids didn't see anything they wouldn't see
walking outside in the warmer months, and just had a pretty typical sports' bar/restaurant experience.
