"I'm So Happy" is Burns' first new outing since appearing on Great Good Fine Ok's "Could Be Us" back in March.

She explains of the new single, "I clearly remember the day I wrote "I’m so Happy" … I went into the studio and was in the best mood ever. I said to the guys about how good I was feeling, and how everything was going right in my life that day - "I’m in love, I have great family and friends, I love my job" and so on. We started talking about the fear that comes hand-in-hand with overwhelming happiness, the worry that something is bound to go wrong, even when it might never. That’s where the idea of "I’m so happy, it’s a problem" came from… the idea that sometimes happiness can be painful, because you feel like you’ve got so much to lose. It’s like being on a tightrope and knowing that one wrong move could cause the end of it all."

She's yet to follow up last year's I Love You, You're The Worst EP.
