The Taylor Swift Chord Progression - 21 songs 1 progression

I first noticed the uniqueness of this chord progression with my first upload here on youtube -getaway car -    • GETAWAY CAR Piano Cover - Taylor Swift   - and was struck by how often these four chords came up again and again in my favorite Taylor songs. I decided to find out how many songs in her entire catalogue use this special chord progression, and found it's 21, more than any other chord progression. Have a listen and let me know what you think. She really is a genius with that minor ii chord. I'll upload a video soon that breaks down the music-theory of why this progression is so special.
