Thank you to Tim for this tip. For some reason something about Zero had made me lose interest in the new album -- Karen O was verging towards self-parody in the clip, for one thing -- but Skeletons is amazing. Its emotion seems so, for want of a better descriptor, superpowered. Potentially, as I was discussing with Tim, the kind of highly powered synthesised emotion, devastating in it in its ability to paralyse through enforced reflection and melancholy, that would have been deployed in Kate Bush's Experiment IV.  Which is, come to think of it, a very emotionless description.
