Theta, a really illuminating post, thanks!  I became obsessed with Dick later and read every one of his novels, excepting the more obscure mainstream efforts.

As a unified work the, one song that stands outside the theme for me is You're Still Beautiful.  I like it quite a bit, but it feels like a diversion.

Disappointment has always been one of my favorites and the central line "I can't find my memory anywhere"  poses Dick's question about human vs android consciousness. It captures the dislocated feeling of not being sure if you are even a "genuine" person or a "genuine fake"(a direct quote from Dick.)   While your senses are occupied by empty rituals and vague reassurances, you can't find yourself in your surroundings, are they just a stage set?
