'The Moon Song' is Karen O's contribution to the soundtrack of Spike Jonze's new film, Her, which also features music composed by Arcade Fire. You can stream the beautifully quiet song, featuring intimate vocals and a strummed guitar, below.

Having previously been nominated for both a Grammy and a Golden Globe for her work on another Jonze project, 2009's Where The Wild Things Are, the loveliness here certainly makes the case for a repeat.
