It recently occurred to me, in an IM conversation, that polka seems like the most out-of-place music I could imagine in a cyberpunk dystopian future. Somehow, the notion of this run-down but exquisitely wired bar (cyberpunk is a very urban fantasy), with the "Pennsylvania Polka" suddenly coming on on the speakers... it seems wonderful and hilarious and wrong (trifecta). I should write Neal Stephenson with the idea.
