It does seem a little bizarre that Taylor Swift's new album 1989 is just 10 days away and there is no official tracklist in sight. Today (Oct. 17), however, it seems as though one has leaked on Twitter. A 16-song tracklist, alongside writers' credits has appeared on the social media site.

Twitter user @luvintothelight tweeted out the 16-song list, which contains 13 standard tracks and three bonus singles from 1989.

In addition to singles "Shake It Off" and "Out of the Woods," the album also reportedly includes tracks with titles such as "Welcome to New York," "I Know Places" and "Wonderland."

Though the tracklist is unconfirmed by Swift and her camp, certain titles do seem legitimate. "Bad Blood," a song rumored to be about Swift's tumultuous relationship with fellow pop star Katy Perry made the cut as well as "How You Get the Girl," which seemed to be sampled in a Diet Coke commercial earlier this week.

A bonus track entitled "You Are In Love" is also included and was co-written by Jack Antonoff. Earlier today, Swift Instagrammed some loving lyrics, which Antonoff's girlfriend Lena Dunham later dubbed her "someday wedding song."

If this tracklist is real, Swift also collaborated with Ryan Tedder, Imogen Heap and Max Martin for her new album.
