Thanks for letting us know your thoughts.
Yes, Taylor may not be the best live singer. Neither are a lot of people these days.
Her lyrics are a little on the immature side. But, hey, she's twenty years old. She wrote all of Fearless when she was younger than eighteen. Self-centered, I disagree. She writes about what she knows, and that's teen love. I highly doubt that every single one of her songs are written specifically about her. I believe that she said "You Belong With Me" was about a friend and his girlfriend, actually.
Lack of depth? Listen to "Breathe," "Cold As You," "Fifteen," "You're Not Sorry," and "Change." "Fifteen" was a single, so you may have heard it. When you listen to it, remember your Freshman year, being lost, and thinking like you have the world figured out. After all, I didn't know it at fifteen.
That's just my opinion though.
