None of them occupied her lane of being “relatable.” She debuted at a time when every artist in pop was selling sex and she was the safe, family-friendly alternative that was doing country music. Combine that with her association to the dudes those young broads wanted, her writing like a diary of her life and the Kanye situation - it was a once in a lifetime sort of phenomenon. If you look at a lot of people who listen to other pop artists, they don’t care all that much about her and being a swiftie is laughed at the way a “belieber” was. Swift hasn’t written a single song that any singer songwriter looks at as groundbreaking. Her winning Grammys directly coincided with people not taking the awards seriously.
Her fans are those “beliebers” “arianators” or whatever else that never grew up and passed it down to the next generation. The closest comparison is Eminem when he blew up - you couldn’t create that confluence of events with any other white rapper again. But unlike Taylor, Eminem didn’t lean into the celebrity and fame game and walked away at his peak to battle addiction. Compare the attention she deliberately seeks with Kelce at games versus Gisselle with Brady or Josh Allen’s fiance who could definitely use it to promote her celebrity. It’s about way more than music - her “fight” with her former record label which wouldn’t sell her masters to her on the low was no different than Drake right now with Universal but she was able to spin it as feminism. She’s the most calculated pop star of all time. I’m saying all this as someone who once operated a blog with someone who took a business school course that used her moves as examples. Respect her team’s business savvy - but let’s not pretend she’s Joni Mitchell.
Taylor Swift didn't debut as a Pop artist though. She came in as Country artist. She wasn't huge out of the gate. She didn't really become big until 2008. To put into perspective Taylor Swift wasn't a factor in 2006. Carrie Underwood was bigger than Taylor Swift. They made a concerted effort to transition Taylor Swift into Pop in 2014 with "Shake It Off".
Kanye, in fact did help cross her over indirectly. After Kanye got on stage and attempted to take her award, people who never knew or cared to know Taylor Swift knew her after that. It started this kind of silent rivalry between her and Beyonce.
She really is the "anti-Beyonce": white, slender, no bass, safe, vanilla. She is to white America what Beyonce is to us. And white America definitely uses Taylor Swift to send the message that they aren't going to let Beyonce break the "glass ceiling" in music no matter what she does.
