Most musicians I have met could easily write a formulaic, vacuous pop song. But they don't. They don't because they do not want something like that associated with their name. They don't want people linking them with music that is cheap, plastic.
However, some of these same musicians will post cheap, plastic content on social media in a desperate attempt to gain followers and attention.
That's like having an organic food company, but posting pictures of dollar store candy because "it might boost my numbers a little."
