I don't particularly care if she's hot or not, and I *do* have the excuse of having a daughter who's obsessed with her, but I've come around to like Taylor. There, I said it.
She's neither particularly good nor bad as a singer or guitarist. What she is, is a first rate modern pop songwriter / collaborator. Very hooky and a lot of them are quite narrative - common in her original genre of country, but refreshing in top-40 pop. Granted she has the usual stable of A-list songwriters at her disposal, so who knows what she'd be like out on her own, but I don't particularly care; there's something distinctive and characteristic about her work, she delivers it very well, and I enjoy it.
