In the background, a song played in reverse, adding to the mystery.
“The vault door is about to be unhinged as you’ll think I am after you watch this video,” Swift tweeted.
Sharp fans rose to the challenge, decoding the messages within minutes and figuring out that at least one song would feature Keith Urban.
At last, Swift announced that fans had cracked the codes and guessed all the “From The Vault” titles.
She also confirmed Urban will be on the new album, along with re-recorded versions of the songs first released on her 2008 album, “Fearless.”
The full list came after an agonizing, weeks-long wait for fans.
On February 11, the superstar, who just became the first woman to win three Grammys for Best Album, announced that the new album was finished, and she tantalized fans by releasing one of its songs, “Love Story (Taylor’s Version).”
In a separate tweet, Swift added, “I’m counting down the minutes til we can all jump into this brave world together, filled with equal parts nostalgia and brand newness. Head first, Fearless.”
