Katy Perry 'Prism' Tracklist Official Released on iTunes, Twitter: Leaked Photo from Listening Session Confirms Song Titles Including 'Roar,' 'Dark Horse,' 'Walking On Air'

The release of Katy Perry’s third studio album “Prism” is just three weeks away. Yesterday (Sept. 30), Perry debuted songs from the follow-up to “Teenage Dream” live, including the never before heard Russell Brand-inspired “By the Grace of God,” at the iTunes Festival in London.

Following that performance, Perry released the tracklist for “Prism.” Dedicated fans of Perry’s will remember that a photograph from an exclusive Los Angeles listening session leaked in September with a rumored 16-song list of song titles. Though that photo was not confirmed as the official tracklist at the time, Perry herself has confirmed its legitimacy when she posted a link to the iTunes store with the “Prism” song titles.

“And yes, FULL track listing is UP,” she wrote on Twitter last night (Sept. 30).

Check out the tracklist for the deluxe edition of “Prism” below.

1. “Roar”
2. “Legendary Lovers”
3. “Birthday”
4. “Walking On Air”
5. “Unconditionally”
6. “Dark Horse” (feat. Juicy J)
7. “This Is How We Do”
8. “International Smile”
9. “Ghost”
10. “Love Me”
11. “This Moment”
12. “Double Rainbow”
13. “By the Grace of God”
14. “Spiritual”
15. “It Takes Two”
16. “Choose Your Battles.”

Thus far, fans have heard four songs from “Prism.” Lead single “Roar” precedes the album, and Perry has released non-singles “Dark Horse” and “Walking on Air” as a part of the pre-order on iTunes. As mentioned, Perry debuted “By the Grace of God” live at the iTunes Festival.

Before the release of “Prism,” the second single “Unconditionally,” is expected to hit the radio.

“Prism” will be released Oct. 22.
