I’m going to argue with the wording of the title.
It’s one thing to say a song would not fly, but the implication is that songwriters still want to write about those things. I would suggest that in 2020 most artists would never write many of these songs in the first place. At the very least, public consumption of many of these songs would be greatly reduced making them unpublishable.
I’ll add Gary Puckett “Young Girl” to the mix… While all those ***** bags like Jeffrey Epstein may enjoy the sentiment, there is no longer a mass audience for that song in 2020.
