"Katy Perry has revealed the tracklist for her upcoming new album. The singer will include 13 brand new songs on her forthcoming collection Prism, which will be released on October 21 in the UK and a day later in the US.  The set features recent global hit &amp;#039;Roar&amp;#039;, as well as Perry&amp;#039;s promotional tracks &amp;#039;Dark Horse&amp;#039; and &amp;#039;Walking On Air&amp;#039;. Further new tracks include upcoming single &amp;#039;Unconditionally&amp;#039;, &amp;#039;Legendary Lovers&amp;#039;, &amp;#039;International Smile&amp;#039; and &amp;#039;By the Grace of God&amp;#039;, which Perry debuted at her iTunes Festival show in London last night (September 30). A deluxe edition will feature an additional three tracks titled &amp;#039;Spiritual&amp;#039;, &amp;#039;It Takes Two&amp;#039; and &amp;#039;Choose Your Battles&amp;#039;. Recently speaking about her next single &amp;#039;Unconditionally&amp;#039;, Perry said: &amp;quot;It&amp;#039;s a love song and it&amp;#039;s different from &amp;#039;Roar&amp;#039; - it&amp;#039;s not eighth-notey. &amp;quot;I think it&amp;#039;s a universal love song that everyone&amp;#039;s going to be able to relate to no matter the age, no matter male or female. It&amp;#039;s my favourite song off the record.&amp;quot; The tracklist for Katy Perry&amp;#039;s new album Prism is as follows: 1. &amp;#039;Roar&amp;#039; 2. &amp;#039;Legendary Lovers&amp;#039; 3. &amp;#039;Birthday&amp;#039; 4. &amp;#039;Walking On Air&amp;#039; 5. &amp;#039;Unconditionally&amp;#039; 6. Dark Horse&amp;#039; 7. &amp;#039;This Is How We Do&amp;#039; 8. &amp;#039;International Smile&amp;#039; 9. &amp;#039;Ghost&amp;#039; 10. &amp;#039;Love Me&amp;#039; 11. &amp;#039;This Moment&amp;#039; 12. &amp;#039;Double Rainbow&amp;#039; 13. &amp;#039;By the Grace of God&amp;#039; Deluxe edition tracks: 14. &amp;#039;Spiritual&amp;#039; 15. &amp;#039;It Takes Two&amp;#039; 16. &amp;#039;Choose Your Battles&amp;#039; Watch the music video for Katy Perry&amp;#039;s &amp;#039;Roar&amp;#039; below:      "^^<http://www.w3.org/2001/XMLSchema#string>
