It's different for every song. But for 'Say Something,' I think it was Chad who had an idea on guitar, and I had an idea on piano for different songs, and we just married them together. We bounce things off each other constantly and kind of massage all these ideas into a three and a half minute pop song.

I feel that when Chad is in the room, I can tap into this other thing where music comes from. I don't know. It's just this really magical, special connection and relationship.

We never thought 'Say Something' would be a holiday song. I'm still surprised that it's resonating at this time of year. Maybe that's why it's working so well - it balances out all the joy.

I started writing songs when I was real young, when I was 3 years old. The piano spoke to me - I don't remember when I wasn't playing piano. My second grade talent show was the first time I performed my own thing. I dressed up as Dracula and played a song called 'Monster Rock' that I wrote. And I won.
