So she did the whole sleep along self empowerment and ballads before. So what's wrong with her stepping out her usual box? As an artist you're supposed to be bold and be willing to try different things. Besides, she is also trying to propel her career and expand her reach. She has to also keep her audience in mind and be a world wide appeal not just for the UK market. A global pop star does this. I can't see why so many people are disappointed.

Do your thing Jessie J!
