* This is a nice enough song I guess, but I don't like her voice on it, it comes across as whiny. Still better delivery than usual I suppose. But what's with her stuttery dragging out of "meee-e-e-e-e-e-e-e-e-e-e-e-e-eeeeeee" among other words? It really ruins the song, and makes it practically unlistenable. Plus there's the way she pronounces "crazy" as "cwazy" multiple times.
But seriously, the dragging out of so many words in ridiculous ways is horrendous, and the "cwazy" gets really annoying, particularly in the second chorus when her voice goes weird. By the end the song is just yelling and dragging out of practically every word. And it's like she's got seven different voices, what a shame they're all terrible. This could have been a nice song if delivered properly by someone competent, instead it belongs to Jessie J and she makes it hideous.
*** The first minute of this is actually pretty good, but after that, the aforementioned vocal 'quirks' come into play which bug me slightly. They somehow got more annoying further through the track too. 2.5
