Karen O's new track "All Is Love," for the upcoming film Where the Wild Things Are, has hit MySpace. The single is a collaboration with Yeah Yeah Yeahs bandmates Brian Chase and Nick Zinner, Deerhunters' Bradford Cox, Liars' Aaron Hemphill and Dean Fertita and Jack Lawrence from the Raconteurs. Digital downloads of the playful tune, which features an untrained chorus of children and a galloping beat, will be made available tomorrow. The big-screen adaptation (directed by Karen's ex, Spike Jonze) will hit theaters Oct. 16, while the soundtrack is scheduled to drop Sept. 29. [Pitchfork]
