I first heard about Taylor Swift when her songs "Love Story" and "You Belong With Me" came out on her Fearless album in 2008. I probably became a true swiftie when I got her Speak Now album on my birthday.  I used to listen to it over, and over, and over.  So, I've been a swiftie for about 5 years.  Thanks @BlinkOfAnEye13 for asking!
