Pretending you're blind and deaf to popular culture (to the extent where you claim to have never heard of one of the best-selling artists of all time) is an order of magnitude more cringe and obnoxious than people who obsess over celebrities.
I'm not pretending, I'm just old. :) Not interested in any of that. You probably realize that there is an age when you just stop caring about all that shit. If not, you will see for yourself later in life.
