Would the be any change of having a “flag” (like a check box perhaps, similar to how “Videos” recordings are identified) for Explicit vs “Clean” versions of a song/recording?
Now, i’m sure one could argue on what basis would you class a recording as Clean, which might be a valid point. Personally, i would say many online music providers flag songs as Clean or Explicit, so that would be what i would base it on.
You could even have such a “flag” on entire albums (releases) as some albums have been released in Clean and Explicit versions for some time now.
This could be used by tagging tools (like Picard) to add the appropriate tag to recordings when tagging.
