I underestimate Taylor Swift's talent! She's good..

At first, I thought Taylor Swift got lucky that her first album become one of the best seller of the year since I think she's got a mediocre voice. But on second album Fearless, the album really explode in US and rest of the world. Started with the single Love Story which airplayed repeatedly in radio stations. I actually didn't like it the first time I hear it, but since it keeps playing in my ears over and over again, I quite like the song. I like her next singles better, White Horse and You're Not Sorry. Also, I think her last single which written by Colbie Calliat, called You're Belong With Me, is very catchy and funny and have a really good video. It's a simple video, but it nicely sums up what the song mean. Although I still think she has average voice, but I salute her cause she writing almost all of her songs, and with all the ex-teen stars from the late 90s has grown up and become overexposed cause their bizzaro behavior (yes that's you Britney and Jessica!), I think it's good to see a good role model that has quite a normal life. So what do you think about her? Do u like her voice or music?
