Australian Sia Furler used to be the front-woman for Zero 7. This song "You've Changed" is quite a bit pop-ier than what I'm used to hearing from Sia, but the video is delightful.
Here's one of her older songs. I think it was in the soundtrack of Garden State. And Blue Crush--that surf movie I can't help but watch whenever it's on. I rank it right up there with Stick It and Drumline. I'm completely serious. I love all of them.
