Soon enough a site will open that is like a Google search for music downloads — downloads that are not copy-protected but you still pay for. eMusic tracks have no copy protection, for example, but their catalogue is limited. Eventually a meta search will turn up the tracks you want, wherever they live, on whomever’s site. Consumers don’t care who they buy them from if the interface is easy and intuitive. Soon enough iTunes consumers will find they have reached the 5th authorized player on their tracks and the frustration will set in when they can’t listen to the music they paid for. They’ll start to look elsewhere.
