The first time i heard this song in MTV, I immediately run in front of my desktop and search for the title of this song. And i'm also a fan of Katy Perry. She is one of the most beautiful performer in our generation. I think she's cool and Sexy in her own way. Most of her songs are my favorites, coz' I can relate to some of her songs, Even though it's not exactly my situation but i can feel her pain, longing, dreams, love, and passion to MUSIC.... i just LOVE her!
