I don't want to sound presumptuous, but I've made it my goal to revolutionize pop music. The last revolution was launched by Madonna 25 years ago.

I sacrifice in my love life and my social life, but those things will be there in three or four years. This is a really important time in my life. I can't just be the girl who sang 'I Kissed a Girl.' I have to leave a legacy.

I wanted to be that quirky girl who writes funny songs that still have meaning.

It's about you putting in the work, practicing every day, and hopefully one day you write the song the whole world wants to get down to. And one day you're going to be sitting next to Ellen DeGeneres talking about how you broke records and rocked the Super Bowl!

The first time I knew what I wanted to do with my life was when I was about four years old. I was listening to an old Victrola, playing a railroad song...I thought that was the most wonderful, amazing thing...That you could take this piece of wax and music would come out of that box. From that day on, I wanted to sing on the radio.

I didn't want to just be another girl singer. I wanted there to be something that set me apart.
