I love Katy, and her voice was mostly on point except for the very beginning a little. I was waiting for the song and performance to pick up, which didn't happen until 3:02, and even then I felt it was lacking something. This is a very difficult song to sing live so I give Katy props for that, but I would have liked to have seen her get more into it and move around, command the stage. Also, I'm not a fan of the pants... But Katy has time to come into her own as a performer. I'm not worried. :]

Something about her tone reminds me of Amerie.

Her band is so well composed with such a diversity of instruments that even match up very well with her soft voice. Love her!
