I might be in the minority here, but I think saying "any theory of physics should explain consciousness" is exactly like saying "any theory of physics should explain love" (or replace love with patriotism, friendship, capitalism, any other human concept). I don't see why consciousness is special: in my opinion it is an abstraction several levels removed from fundamental physics. In other words, to a neutrino flying through you, you are only barely distinguishable from empty space, and your consciousness (and love of music, appreciation of art, etc) means nothing.
