Listen: Karen O - The Moon Song

Long time collaborators (and ex-partners) Karen O and Spike Jonze have teamed up for the first time since Karen O compiled the sound track for Jonze' interpretation of Where the Wild Things Are. His new movie is called Her, and depicts Joaquin Phoenix's love affair with an artificially intelligent operating system (Scarlett Johansson). The score has actually been compiled by Arcade Fire, but Karen O contributes this delicate number 'The Moon Song', which you can listen to by itself or in the trailer, below.
