The irony of all the criticism of shake it off is that the song is actually very clever. It's her shaking off the way she was portrayed in the media - slut shaming, blonde bimbo etc. I remember at the time (before I was a big fan) thinking "this girl doesn't care what you think, she knows her own worth".
A few have mentioned Amy Winehouse. Yes, she was incredibly talented, she was also very troubled. Taylor is, to me (and millions of others), just as talented but has proven how strong she is too. No she hasn't battled drug addictions (good for her), but she hasn't had it easy either despite what people think.
Taylor was cancelled in 2016. This was due to a culmination of criticism and oversaturation in the media (she's overexposed atm too probably, but I don't think it will harm her this time) and Kanye West and Kim Kardashian trying to ruin her career. They told lies about her and recorded a phonecall with Kanye and Taylor, choosing only to release clips of the parts that suited them. The full recording was leaked in 2020 (probably by Kris Jenner) and Taylor was proven to have been telling the truth the whole time.
She was hardly seen at all for a year from sept 2016. She met her ex (of 6 years) around then and kinda hid away with him. But she came back with the aptly named album reputation in 2017, Look what you made me do was a response to the whole thing. I love that song but I get why others don't. The video is incredible though. Anyway, she fought back. She always fights for things she thinks are right, stands up for herself. Her row with Spotify, sexual assault case, reclaiming her masters.
So many female artists these days are overly sexualised also, whether it's lyrics, dance moves or clothing. Even Taylor's songs about sex aren't vulgar, more sensual. And she definitely keeps things a bit classier than most (without being prudish). I just think she's a fantastic role model for all females.
