Taylor Swift honored a very special Eras Tour anniversary with a never-before-seen video from the beginning of the legendary tour, and fans think she is teasing Reputation as her next re-recorded album.

The iHeartRadio Awards played a "Folklore" surprise song from Taylor Swift's first tour date in Arizona two years ago.

As a bonus, Swift released never-before-seen footage of her performance of "Mirrorball" on opening night of the Eras Tour in Glendale, Arizona. The Eras Tour kicked off two years ago on St. Patrick's Day, and "Mirrorball" — from her Evermore album — was one of two surprise songs performed that first night.
