Ready or not: Taylor Swift has released the official titles of her songs off her highly-anticipated sixth studio album, Reputation.

And most notably among the 15-song tracklist is the 27-year-old singer's (one and only) collaboration with BFF Ed Sheeran and rapper Future, titled "End Game."

The forthcoming single will mark Swift and Sheeran's second single together following 2012's "Everything Has Changed" off her Red album.

The tracklist, which Swift posted on Instagram just hours after it was leaked, also listed production credits of which the Grammy winner is tagged as executive producer. Co-producers include Jack Antonoff (“Out of the Woods”), Max Martin (“Shake It Off,” “We Are Never Getting Back Together”) and Shellback.

Reputation is the singer’s follow-up to 2014’s critically acclaimed pop masterpiece 1989. When she announced the newest album through social media on Aug. 23, Swift also gave us a look at the meme-worthy cover art. The fonts that make up the album cover are notably similar to those used by publications.
