Taylor Swift could play five three-hour concerts without repeating songs + my wishes for the “surprise songs” on the first night in Zurich

Your numbers may vary, but there are 232 tracks on 11 albums in my Taylor Swift music collection, with a few duplicates, such as two versions of "State of Grace". It  comes to fifteen hours and twenty minutes of music in all. Her concerts on her Eras Tour are three hours and fifteen minutes long, so she could do five such concerts with few or even no repetitions of songs. (This is how a Deadhead thinks, of course.) But the current setlist includes 44 fixed songs plus two "surprise songs" at each concert. Tomorrow in Zurich, I'd like to hear "New Year's Day" and "When Emma Falls in Love" as surprises.
