Cover art for Machine lyrics by Regina Spektor

This part:

And I'm downloaded daily I am part of a composite

makes me think of Making Records.

I think that she could be talking about her computer as the Machine. She's "upgraded daily" and has "friends in high places". The correspondence who "just lacks my perspectives and who lacks my organics and who covets my defense" I'm thinking e-mail. Letters without feelings. Everything's provided - we're not doing anything ourselves, and because of all this we forget the worldly troubles. pre-war or post-war: we never notice. We just see our own future and our machines...

OK. a bit hard to follow maybe, but I think this is a possible interpretation.
