Based on similar videos by red pig and Greg Heffley.

Every time Taylor Swift (or featured artists) sings the name of one of her songs in another song. This includes non-album tracks, but does not include covers and songs where she is a featured (not primary) artist. I also excluded Ronan and Soon You'll Get Better because they don't belong in a silly video like this. Finally, I didn't include every time she sings "ME!" because that would be editing hell and make the video like 20 minutes long.

Shoutout to this website, which I used to search her lyrics for song titles and greatly reduced my workload: https://ts-lyrics.netlify.app/
