I interpret the article to be referring to parents of young children (e.g. identifying parent listeners via kid/nursery music). These parents may well be curating their non-kid music listening for their children.

That's what I did. When our kids were born, I wanted them to hear historically-significant popular music, not just the currently popular dreck. Think Motown or 80's Michael Jackson, not {fill in the blank with anything popular this minute}.
