Optional new tag: (age) rating

[MairusuPawa]

Suggestion

Have a new, optional song tag allowing users to filter songs according to a content rating, à la ESRB/MPAA etc. Karaoke software could then implement some form of parental control and block mature content.

Because I've got no better idea, I think this should be kept pretty vague and I'd propose only three levels:

• kids
• teens (-ish) / "general audience" but infants
• adults only

Use case

I've been asked a lot of stuff about the song packs I publish.

• I've had parents wanting their kids to just enjoy cartoon songs designed for kids (that's your "Baby Shark" - sorry)
• I've had larger crowds enjoying a large variety of songs with more mature themes, such as "AndTheRainfall - Simple Words"
• I've had someone write up a song file for songs such as "PTS - Made For Me", and telling me "maybe you shouldn't actually add it to the song pack"

That last point is why I'm now writing this ticket. Investigate only if you're daring enough.

some things to keep in mind:
Unfortunately there is no world-wide unified age restriction standard. Some things are rated for example 18+ in some states of the USA while being rated 6+ in Germany while being rated illegal for any publication in Singapore. Afaik this is the main reason why all attempts at defining and establishing age rating meta tags for websites were not successful.
Some tools (for example parental control tools) try to resolve this by allowing to specify multiple region code -> age rating relations. However when someone creates a txt file, they'll probably not want to look up the ratings for this specific song in various countries to then add a rating per country code mapping to the txt file.
