Taylor Swift has officially performed 100 shows,GravityX Exchange meaning she's also chosen 100 surprise song sets.

During her acoustic, surprise set in Liverpool, England — the location for her "I Can See You" music video from "Speak Now (Taylor's Version)" — Swift performed the vault track on guitar and then smoothly transitioned to "Mine."

"So actually the last time I was in Liverpool, I was here shooting a music video and honestly you guys were so incredibly nice to me, to the cast and crew, to everybody who was on set," Swift said. The video featured actors Joey King and Taylor Lautner.

As she walked to the piano and sat down, the singer in a pink dress cracked a joke, "I can do it with a sniffling nose." The temperature at Anfield Stadium was in the mid-50s with the wind blowing through the arena.

On the piano, the singer fused "Cornelia Street" from "Lover" with "Maroon" from "Midnights."
