Open the blinds and let the light in: Katy Perry‘s Prism snippets have arrived on iTunes.

From “Roar” to her trap-tastic “Dark Horse” to her CeCe Peniston-inspired “Walking On Air,” we’ve already heard plenty from her mixed bag of an upcoming studio album. Now, it’s time to sample the whole damn thing.

Listen to all the snippets on iTunes now.

My thoughts on the music are more or less the same as when I first heard the album during the Prism listening party in Los Angeles last month. However, we didn’t get to hear the deluxe edition tracks during the playback — “Spiritual” sounds quite promising so far.

Let me know your thoughts, favorites and, undoubtedly, all your complaints and criticisms below.

Prism will be released on October 22. (iTunes)
