Keeping tabs on the songs (it's all very deliberate, apparently): Episode 2 -- Radiohead, No Surprises @ 24:35 -- I had to look this one up, too, but at least I recognized it right away as a player piano/orchestral rendition of a contemporary pop tune.
I love what they did with the Thandi Newton character, "bump up her aggression" (and she practically grabs a guest by her pussy), and then turn up her emotional acuity just a tad, and she becomes just right?
