I mean, I didn't develop my own musical taste until my mid-20s. My parents only played Christian worship music, while all my friends in highschool and university were various flavours of music snob. I was literally convinced that no one actually liked pop music because everyone I knew seemed to hate it.
I don't know if I was ever a "people pleaser," in that I never pretended to like a band or song just because everyone else did. However, I definitely avoided saying anything negative about the music I was exposed to for fear that I'd be ostracized all the same.
It took me a long time to overcome all that, and it took even longer to admit my tastes publicly.
