I've written some happy songs but I can't ever play them in public because everybody will just start throwing up.

And the thing about me is, I have a lot of mellow songs, because they're the easiest for me to write. I wanted to try to make some more upbeat songs, so, I ended up gravitating toward writing songs with friends, which was a great learning process, and also we came up with great songs. Those are the songs that came out the most naturally.

Because when does anybody really grow up? I mean, I feel more grown up now, more in a place of solidity and peace. But I think a lot of people take on these roles as parents, or husband or wife, and immediately think 'That's it. I'm grown up now. Done.'

Growing up in a multicultural family, I never really felt that I was different - even though I was from most of the kids in my school. Especially with music, I try to just approach it as an equal.

I wasn't sure if I wanted to put that out there so blatantly, so that before you listen to me you know that I'm Asian. But I thought it was sort of cool to embrace the Korean half of me, which I love.

In whichever way my music can get out there, I'm just like, 'Sure.' It's also through the TV synch licenses that I've been surviving. I don't really make money through record sales. I used to be really picky: 'No, I don't want it to be the song of a commercial,' but nowadays it's what you need to do to get the song out as much as you can.

With some artists, I've noticed that after their songs have been licensed, on their next album you can totally hear they're trying to write a song for 'Grey's Anatomy' and it doesn't work. It's just one of those things that has to feel genuine to last a long time.
