 :::::Frankly, I think that the nod to the Holocaust theme was simply not there. Without a visial linkup to the concentration camps (at least, not w/out using OR) or having familiarity with the song (and one has to listen very, very carefully) to even hear the words 'arbeit macht frei,' the reference doesn't even belong. We aren't talking about the Shantih, Viriditas - that has already been determined in prior posts here. That being said, at least there was a clearly observational component to it. The arbeit macht frie reference is nowhere near as clear. A pity that Cuaron didn't have it spray-painted inside of Bexhill or something; simply having a song wherein the words are barely audible after the third listening doesn't seem to arise to the standards necessary for inclusion. I think it should be purged altogether as it cannot be referenced outside of one reviewer's reference that it is playing subtly in the background.
