Do people fake their music tastes to impress people?

As a teenager I used to live with my cousin every summer and she has good taste in music, she liked Toni Braxton, Natalie Merchant, Gloria Estefan, the Offspring, Madonna (In the 90s). Her music was always good. When she was in her early 20s she gave me a burnt CD of some musicians and it was all pop and hip hop junk that tasted like processed garbage and there is a plastic surgeon from my high school who posted years ago she liked lady Gaga on her public profile, I think she is faking it to fit in, why would a plastic surgeon choose lady Gaga over Mozart or Beethoven?
