I have a serious addiction to Taylor Swit. I know that her voice isn't the greatest when it comes down to it, but her lyrics and the way she sings makes it good music. Her voice is interesting, her lyrics are simple but usually wonderful, and she has a great energy. There aren't many of her songs that I don't or didn't like at one point. I have a tendency to become obsessed with one of her songs and slowly wane off of it, losing it's appeal to me, but then she releases a new song and I become obsessed again.
All in all, I think she is great. (:
