Hmm. Thinking about this. Your point sounds really good but I think there's a logical fallacy here. That most people like something doesn't make it ordinary. Were The Beatles' pop songs ordinary?

I am not a Taylor Swift fan. That's not a critique of her. I wouldn't recognize one of her songs. So nor am I defending her here, though I think what I read about people bashing her for the lyric about how she would have liked to have lived in the 1830s but without racists miss her point and are just looking to criticize.

Back to your point here, I think you have turned the concept of "the bandwagon fallacy," which Douglas Giles PhD wrote about here, https://dgilesphilosopher.medium.com/the-most-pernicious-logical-fallacy-0d88550f2b75, on its head. Just because something is popular doesn't make it false.
