Jessie J is obviously a fantastic singer and she really does use her voice as an instrument. Although this song doesn't demonstrate her vocal ability as such, the vocal melody is strong and extremely catchy. I love the overall feel of the song; upbeat, with a positive feel and consistent beat all the way through, keeping our feet tapping and her smiles wide. This isn't just a typical pop track; it's a great one, don't get me wrong, but as always, Jessie J tries to mix it up a bit; The guitar solo in the instrumental makes the song more interesting and adds a little bit of spice to an already flavorous song. It also has an important meaning: being a sexy lady isn't necessary what other people think but what you think about yourself! Jessie J always delivers and if this is a song to make her fans/listeners feel happy and press reply, then she's done her job!
