The song was released on 19 May 2005 as the first single from her second album Speak for Yourself, and was written and produced by Heap. It is an a cappella folktronica ballad which makes heavy use of the harmonizer, written about painfully losing someone.

The song also appeared on NPR's 2018 list of The 200 Greatest Songs By 21st Century Women+.
