Ever since the first night of Taylor Swift’s Eras Tour — when the pop star announced she’d be performing two surprise acoustic songs at every show — fans have been waiting with bated breath to find out which gems from her discography will be unearthed next.

Swift kicked off the tour in Glendale, Ariz. with “Mirrorball” from “Folklore” and “Tim McGraw” from her 2006 self-titled debut album. Since then, she has surprised audiences with songs including “State of Grace,” “Our Song,” “Cowboy Like Me” with special guest Marcus Mumford, “Sad Beautiful Tragic” and “The Lucky One.”
