The song sounds great, and they sound great together! I like the CD + DVD cover, but that CD only is so awkward for some many reasons.
Its just so awkward it makes me think they took those images separately and then in post production the photographer or graphic team just composited them together. Aside from CK's floating foot, looking at Namie's foot and CK's other foot, they don't look like they're solidly on the ground either.. but I could be wrong. I suppose since it is more CK feat Namie... they would make CK look better? Not that she looks much better in the shot, its just bleh. They got it right on the CD + DVD thought.
Looking forward to hearing the full length version.
