Which songs from Katy Perry’s ‘PRISM’ sound like they’ll be your favorites?

Our early favorites may be the first few songs on the album because they seem like they’re the most radio-friendly. Our top choices right now include “Birthday” and “Legendary Lovers.”

In recent weeks Perry has released “Roar” (the first and only single so far), “Walking On Air,” and “Dark Horse” for purchase. Interacting with fans on Twitter this morning, when Perry saw a tweet from a fan who said “Unconditionally” is “the best song on the album, Perry replied, “Oh good! You’ll like this week then.” That comment from the singer may suggest it’s the next song to be released in full, or Perry will be performing it live at an upcoming appearance.

PRISM‘s standard album is available for $11.99, and the deluxe edition can be purchased for $14.99.
