In the past couple of days, when I was busy, I thought about one thing:
Most likely, the reason why there is NOT surprise songs this tour, is that, Taylor wants to perform every single song from the album, including deluxe edition. This is a good idea, but because of the time, fans can not go back home too late, so no time for surprise songs.
But how about this:
Instead of only switching from WONDERLAND to YOU ARE IN LOVE, put other 2 songs on the set-list into the same situation, it means choosing TWO other songs (third and fourth after WONDERLAND and YOU ARE IN LIVE) from the set-list, and switching between them from concert to concert.
This will save one song for surprise from Taylor's previous albums (Covering other artist's songs if you guys prefer).
How do you guys think about it? Choose which songs to switch? Which songs to be surprise songs? Which songs to cover?
I'm here for LONG LIVE

as surprise song in MetLife stadium.
Edit: You know, I lost twice already guessing which of WONDERLAND and YOU ARE IN LOVE would be performed. If I have 2 more songs to guess, it will be more fun.
Edit2: Most importantly, we will have SURPRISE songs again. which in my view, is one of the best parts of Taylor Swift concerts, besides special guests.
