Looking at Folklore on wikipedia Antonof or Dessner are on most of the tracks. Do I think she took a couple of Indie music people to help her write/produce etc songs in a new style? Clearly. Does that actually mean she just added a word here and there though? Trying to infer whether on not Taylor Swift writes her own songs based on consistent collaborators seems odd to me.
