Taylor Swift's newest album "Reputation" was finally launched on Friday, Nov. 10, but days prior, Swift released the album's complete track list following a leak from a store in Birmingham.

The 27-year-old singer posted the titles of the 15 songs on her Instagram, revealing 12 yet-unheard tracks.

The song list was followed by productions credits, which named her as the executive producer, as well as co-producer with Jack Antonoff, Max Martin and Shellback. The album was mixed by eight-time Grammy winner Serban Ghenea.

The post also confirmed her rumored collaboration with "Perfect" singer Ed Sheeran and rapper Future for the single "End Game."

Swift's sixth album had been clouded in secrecy, with the singer letting her music do all the talking. Promotion for "Reputation" had been the complete opposite for her "1989" album, which was released in 2014. Back then, she was all over the news, getting interviews left and right, to raise awareness for the album.

Now, she is wisely spending her time away from the media by meeting her most loyal fans called the Swifties. Her social media updates are short but sweet. And while she doesn't talk in public much, her newly-released singles "Look What You Made Me Do," "...Ready for It?" and "Gorgeous" are saying everything she wants to say with their meaningful lyrics.

However, to the surprise of her many fans, the complete record was played in an HMV store in Birmingham a few days before the album's release. Her albums had been earlier shipped to retailers in preparation for the release, and a staff reportedly played Swift's album, not knowing that it was not allowed yet.

The store has since received backlash from Swifties who could not believe they could commit such a glaring mistake.

Prior to the release of "Reputation" on Friday, pre-orders had already exceeded 400,000. According to Big Machine Records, this is double the amount for "1989." Target also said this is their biggest music pre-release of all time.
