This song, cowritten and produced by Imogen Heap, feels like a fresh start. A clean slate, if you will. It's about how whenever you go through trying times, whether that's a breakup or something else entirely, there's eventually a moment of release where you feel OK to move on. I've listened to this song on some of my darkest days, and it never fails to make me feel just a little more healed. "Clean" is as relatable as it is beautiful, a gentle reminder that when you feel overwhelmed with emotion, you are strong enough to get through it.
