NEW YORK -- Katy Perry says although she's "older and wiser," she still plans to have fun.

Perry debuted 12 songs from her new album, "Prism," to be released Oct. 22, in front of an audience of 100 industry insiders and journalists Thursday night in New York. The beat-driven album features likable, radio-friendly tracks, much like her multi-hit 2010 effort, "Teenage Dream."

The 28-year-old pop star played songs like the '80s-inspired "Birthday," which she called "something like Mariah Carey would have put on her first album." She said "Unconditionally" was her favourite song and she was proud to have written it. "Dark Horse," which features rapper Juicy J, sounds like a Southern rap-techno mashup.

Perry's first single, "Roar," bumped Robin Thicke's "Blurred Lines" from the top spot on the Billboard Hot 100 chart this week. She debuted the music video for the track Thursday.

"I'm very excited to bring visuals to a lot of the songs and play them live," she said.

"Prism" features producers Dr. Luke, Klas Ahlund, Sia, Bloodshy, Greg Kurstin and others. Some of the new tracks include emotional lyrics. She sings "one man's trash is another man's treasure" on "Double Rainbow," and on "By the Grace of God," she sings "wasn't going to let love take me out that way."

"Prism" will include 13 tracks; its deluxe version will have 16 songs. The singer was excited and playful at the event, and even cracked a few jokes. She said the album was due at her label on Monday, but not all of the tracks were mixed.

"It's the 'Prism' preview. I wanted to show you what my prism can do," she said to laughs.
