American singer-songwriter Taylor Swift has announced the third and “final” special edition of her upcoming album ‘The Tortured Poets Department’ with an extra song like the previous two.

“I kind of wanted to bring you something that nobody else has seen,” Swift told the audience before unveiling “The Black Dog” during the surprise song set at the second concert of her Eras Tour in Singapore on Sunday (March 3).

As Variety reports, the title of “The Black Dog” will intrigue fans who know it as a popular expression for depression or melancholy, which is said to have been first used by British author Samuel Johnson in 18th century and became widely known in the 20th century by Winston Churchill.

Moments later in a post on social media, she presented the black and white cover of the new edition signed by Beth Garrabrant as well as an excerpt of the lyrics “Old habits die screaming…” in the caption.

This vinyl version will be released in black and will be available until March 6th from Swift’s online store. ‘The Black Dog’ joins the album’s bonus tracks, ‘The Manuscript’, ‘The Bolter’ and ‘The Albatross’.

The album ‘The Tortured Poets Department’ will be released on April 19th.
