I really enjoyed Arcade Fire's original score for "Her," but why didn't Warner Bros. release it?

I read here that they wouldn't release it. They had it available for streaming but since it's been taken down (and been nearly a year after it's release) I've wanted to find it. It really complements the film, and in my opinion should have been nominated for an Original Score Oscar. Any ideas why? Do you think they'll ever release it or make it available for download?
