The sleeper hit has been a fan-favorite since the album first dropped, but it didn't become a single until The Eras Tour, which features the track in its opening number, boosted its popularity.

With the release of Swift's concert film on October 13, the song has gotten yet another push on the charts.

The Karma artist also helped the track inch toward the top spot with a new EP titled The Cruelest Summer, featuring a live version from The Eras Tour and a new remix.
