> I still could not accurately identify one of her songs by audio if my life depended on it OR if someone offered me $100 million I'd definitely lose out on that money.
Both this comment and the comment it's responding to are indicative of people living in their own bubbles. It's entirely reasonable that plenty of people just don't expose themselves to contexts where they would have had any opportunity to hear any given musical genre. This is easier than it's ever been since the invention of radio, thanks to the fracturing of culture via recommendation algorithms and the long tail that the internet facilitates.
An even easier way to not be familiar with her: living in a country where she's not that important: <https://chartmasters.org/taylor-swifts-global-heatmap/>. So it's pretty easy in: Chile, Switzerland, Italy, France, Argentina, Costa Rica, Spain, Netherlands, Southern America in general, Eastern Europe, Northern Europe... Lots of countries really. Living in a given country is not much of a bubble. Imagining that pop stars popular where you live are universally popular is very much a bubble.
If you don't listen to the radio, how could you hear them? I'm probably in the only demographic that doesn't have swifties, most people my age streams movies and uses adblockers so I honestly couldn't identify a song by her if I didn't write her name in Youtube just to see what the deal is.
Music is so fragmented these days that there's no comparison to Pink Floyd and Rolling Stones days.
