Spike Jonze's film Her features a simple guitar duet between Joaquin Phoenix and his OS love interest (voiced by Scarlett Johansson), titled "Moon Song". Yeah Yeah Yeahs frontwoman Karen O, who co-wrote the track with Jonze, also recorded a solo studio version. Now Rolling Stone has a version of the song that features Vampire Weekend frontman Ezra Koenig opposite Karen O. Per Rolling Stone, there's a three-song Moon Song EP coming on iTunes this week.

And: "The Moon Song" is nominated for an Oscar. "It's wild because 'The Moon Song' was written and recorded in the most humble of circumstances; at my dining room table, a few paces away from the couch I read the script for Her for the first time," Karen O told Rolling Stone. "I was really excited at the prospect of getting to record it with a male vocalist. Ezra was super cool and open, he slipped into character like a champ and damn he's got the goods."
