I like some of her earlier stuff. Little Earthquakes and Under the Pink are fine albums. I'll have to admit I'm not such a fan of her covers, but I agree with Lee that it's a cool way to cover someone - by deconstructing their song and putting your own spin on it rather than just producing a copy.
It's sad that she's become another victim of too much plastic surgery because she was quite the cutie back then. Her somewhat large ears and slightly big front teeth only made her cuter, realer and a little unique.

It's just sad that someone as beautiful as she was ever felt the need to fix herself up to start with when there was absolutely nothing wrong.
