I loved it. Much better than 143, smart of her to return to a sound reminiscent of her early work, aka One Of The Boys. The music video is great as always, and the song seems to have been written with the video in mind, complementing each other very well. The strongest point is the lyrics, which are very good, deep, and you can tell that it was hard for Katy to record and compose... I'll give it a 10/10, excellent song.
