Should concerts have movie-style parental ratings?

Dozens of parents were spotted storming out of a Ke$ha concert in Windsor, Friday night, kids in tow.

No, not because of the terrible music, but because the concert, advertised as "all ages," featured explicit lyrics, profanity and sexually-suggestive content that clearly wasn't appropriate for kids under the age of 18.

Parents assumed the concert, which took place at Caesars Windsor, would be a toned-down version of the controversial musician's show because it was billed as "all-ages." Kids as young as eight or nine years old were in attendance.

Parents were outraged. They left the show and posted complaints on the Caesars Windsor Facebook page and website.

“Why was this show open to all ages?? So not appropriate!!!" wrote one angry parent.

Caesars Windsor responded:

We appreciate that Ke$ha's show may be offensive to some which is why signage was prominently posted to caution the audience.

It is ultimately up to concert attendees to review an artist’s material, before purchasing tickets, so that they may make their own informed decision on what is age appropriate, as this is subjective. What may be offensive to some is acceptable and enjoyable by others.

One possible solution to this issue might be to give concerts parental ratings like they do for movies — if a show is given a "G" rating, it's suitable for all audiences, whereas an "R" rating would require children under 17 to be accompanied by a parent or guardian.

So what do you think? Should concerts have movie-style parental ratings?
