As a fellow enjoyer of heavy/extreme music, I appreciate a well-written song in any genre, and I'd say her talents are far more along the songwriting vein. She's a reasonable musician, but her ear for hooks and her lyricism are far more remarkable than her musicianship.
If anything, you might like Cardigan. I've enjoyed metal and some rap most of my life, and I find that those are more about the lyrics than the melody (but obviously the melody matters). Cardigan is one of her best lyrical songs, IMO.
If that's a serious question, I think Lover is her closest album to something like that. It's a pretty fun mix of modern electro-pop songs with some decent lyrics.

I wrote that Lover is the closest to synthwave, but that was before I listened to some of Midnights with my daughter in the car. Midnights is very synthwavey in a The Weeknd/Billie Eilish way. Probably you were just making a joke and aren't actually interested, but in case you are, give the whole album a listen. You might actually find something you like there.
I've tried, and her music is fine but it's just not convincing enough to relisten, and absolutely nothing she's made justifies the cult like obsession from swifties.
As far as female pop singers go, I'd much rather listen to Purity Ring. Or any jpop/jrock outfit with a female singer for that matter.
