"(Talks about Lucky You) "The song was about a girl who didn't fit in and she didn't care and she was different than everyone else. I think there's a long chorus of me singing "Do do do do do do do do do do". It's very young and I look back and it's kind of interesting to hear those kind of storylines and the lyrics that I used to write compared to the lyrics that I write now."
