Her earlier music is very derivative and can easily be seen as very generic, not much done in the creative process. I like the last 3 albums much better.
As for artist of the year, not saying that she didn't deserve it but there are many artists who didn't win cuz they aren't as famous as Taylor, we all know how those politics work.
Her fan base is also very toxic, they even disregarded Lana Del Ray's award for artist of the decade or smth like that similar to Taylor cuz they THOT Taylor should win.
I'd happily prefer The Weeknd over Taylor, even though they are very similar in terms of popularity
