I keep listening to this song. It's sexy, sad, and you can dance to it. What's not to like?! :-)
At first the vocals reminded me of Bjork, so I thought they were Icelandic, but it turns out they're Swedish, the magical land where tons of great beats, djs, singer songwriters, and bands have come.
I like the vacillating between killer synth-groove and heart-breaking wide-open wail.
