Yeah this is ridiculous. One of the songs you posted has a key change so if you're saying a key change is fundamental for expression you're clearly not listening hard enough. You also didn't do a great job trying to explain the appeal of it, likely because you don't like it, as you will never be able to capture the fire like someone who does, so it just comes across as condescending. As well, likening her to "Taylor Swift but Louder" further shows your lack of knowledge about pop theory and history.
The rapidly moving pace of the music and performances in those two performances (2 of her hits, of course they're intense) is because she believes those were the more interesting/economical choices at the time. any inferences you make about the women who listen to it are purely based on your personal idea of what you decide women are thinking about on a given day.
Taylor Swift did well understanding the emotions of teen girls, so well that lots of teen girls, not just in the US, begged their fathers and got ~$1000 for a ticket to a Swift concert, and Swift ended up worth ~$1 billion.
It also helped that with good makeup and a good photographer, she had one of the prettiest faces of any human female. She also had a near perfect figure. So, her audience could identify with those. Likely even more important, were her stories of love gained/lost.
I'm a man and so don't much like Swift's art, but the ~$1 billion got me to try to explain her success.
For any men here slow to figure this out and take it seriously, a lot of teen girls and young women have some strong emotions, and art that communicates and interprets those emotions to those teens/women can be very welcome, so welcome to generate ~$1 billion.
I did spend enough time with teen girls and young women to understand a little about their strong emotions.
On key changes in music, the Bach piece in the URL I gave starts in D minor, has central section on D major, and has the final third a lot like the first section and also in D minor.
When I was playing it on violin, I liked the D major section the best. There are some triplets, and I played them insistently, maybe not the best interpretation -- the URL doesn't do that. Maybe I tried the interpretation from a Heifetz performance.
The piece is also sometimes played on guitar. Waiting for a concert to start, a guitarist sat next to composer Mario Castelnuovo-Tedesco and said "The Bach Chaconne sure is difficult to play." The composer, a man of few words, said nothing until the end of the concert and then replied "The Bach Chaconne is the greatest piece of music ever written."
Oh, the URL I gave is a full orchestra arrangement of the Chaconne.
If pop music is that good, I'll be glad to listen to it!
