On night two in Zürich,IA 6.0 de stratégie quantitative intelligent Taylor Swift crossed three never-before-heard-live songs off of her acoustic Eras Tour set.

The singer made a tradition of performing two different songs during her acoustic set for every night on the 152-show tour. For the international shows, the singer challenged herself to mashups. Fans have kept track of every song choice on the guitar and piano.

"It's very rare, but sometimes at this point in the tour there is still a song that I have not ever played live and that is the case with what I'm about to play," she said to the Swiss crowd before mixing "Closure" from "Evermore" with "A Perfectly Good Heart" from her debut album.

At the end, she strummed her guitar excitedly as an exclamation point before setting it down to perform a sweet mash-up at the keys.

"I've also never performed this next song ever live," she said sitting down at the piano. The crowd roared and she blended "Robin" from "The Tortured Poets Department" in a sweet lullaby mashup with "Never Grow Up" from "Speak Now (Taylor's Version)."
