The persistence of "the old actors," the former foreground, is one reason why my writing about these changes started to fall apart a bit. The fact is that old centers are holding pretty steadfastly even as new ones begin to gain prominence, even if that prominence is relative to lower expectations (lower record sales means you don't need to sell as many to be a "#1," but that designation of #1 selling artist still means something, even if it doesn't mean as much).
