I know lots of people don't like him as a musician but when he said he's been studying about her music, details in her videos and movement, that's a huge compliment for Taylor
After Style/Wildest Dream/Bad Blood
My picks are :
1. I Know Places. She should give another producer's chance. And it sounds like a smash, dramatic, haunting, yet so catchy, although it maybe becomes slow burner too, like Ghost or Counting Stars. It's so different too with her previous singles
Problem : Its chart position in iTunes is miserable. Taylor should realize, this kind of song wont smash in few weeks, but once it smashes, it will smash really hard
2. New Romantics / Wonderland. I dislike the latter. But it's like Australia's favorite ( or I hope, it's just a glitch ). She should release track from deluxe version too, like she did with Speak Now. They sound different, unlike HYGTG or AYHTDWS which are boring and too safe
Problem : Will she release them or snub them like Red's deluxe tracks?
3. Out Of The Woods. She usually releases promotional single as single. And IMO, OOTW is like Fearless or Red of 1989, and it reflects 1989's concept. The end of the song sounds triumphant, great as closing single, although it probably gets tour footage video treatment.
Problem : it's kinda underperformed now at iTunes
IKP is my fave out of the 3 but idk whether it would smash
