None of the AOTY noms have a good case for winning because no one knows what the Grammys are rating. I can't have a good case for NBA MVP if no one knows what the MVP means. But with that said, as someone who watches critical reviews, Swift is an amazing story to me.
MJ was critically acclaimed so no one batted an eye when he one. No one is talking about pop stars winning, but she is genuinely acclaimed by pop critics and then you hear bad blood and go what the fukk? There was a time when the Grammys literally thought about overhauling the voting because Lionel Richie beat Prince and Bruce Springsteen. Critics hate Perry, Rihanna, etc.
But 1989 which is basically a Katy Perry album is AOTY material? Her "advanced" songwriting is a talking point created by her PR because she was young and writing parts of her songs. But the songs themselves are generic. Do you want me to post song lyrics from the Grammy winning album of the year of 19/20 year old Taylor Swift?
This gets you compared to Prince and Joni Mitchell? Come on dawg. These are Disney Channel Original Movie caliber records. The one thing you're right about is the media landscape is different. The hating old rock nikkas have been replaced by people who feel like they have to rate popular shyt highly. Everyone I know in the music industry "begrudgingly" gives her props like you said, but it's more respect for her PR game than music.
