Hold on, do you think most music has romantic subplots?
Because the original argument is that a movie about giant robots fighting doesn’t necessarily need a romantic subplot tacked on. It’s not saying a Valentines Day romance movie needs to stop shoving romantic plots down our throats.
Maybe I’m just not well versed enough in music, but as far as I know, music producers aren’t out there saying, “and now the big kiss… and moving on”.
That’s the business model!
