Swift – who is engaged to Travis Kelce, also 36 – writes to please her own tastes, rather than to match up with expectations and she is “okay” if fans don’t like some of her songs.
She said: “Oftentimes when I love it to a certain degree, that tends to match up with people.
“And it could be that it doesn’t match up with the way people feel until six years later.
“I loved the Reputation album. I was like, ‘You guys say what you want. I know what I did. I love it. Go with God. Sorry. You can come around if you want. It’s okay if you don’t.’”
Swift also recalled how her latest song Elizabeth Taylor was inspired by a passionate rant during a car journey with Travis.
She said: “There are so many different ways that a song begins in my world ...
“I’m riding in the car with Travis.
“I go on and on in explaining to Travis, like, why I love Elizabeth Taylor so much. ‘She fought for artists’ rights. She was exploited in so many ways, and yet she kept her humanity. She kept her humour. She kept her passion for life.’ I was just going on and on.
“I was like, ‘Her eyes were violet. Some people said they were blue. Some people said they were violet. I think they were violet.’ We get home. He gets out of the car and I’m just in my head just this intrusive melody ... And I’m just scrambling to open my record app on my phone.”
