Taylor Swift couldn't fit her entire three-and-a-half-hour concert into Taylor Swift: The Eras Tour, so she had to sacrifice a few songs, and unfortunately, they were the wrong choices to leave out of the movie.

Instead of promoting her newest album Midnights, she created the Eras Tour, a celebration of her life's work.
