I agree that "something will change" but in terms of how recorded music is "published" I don't see a complete reversion to "singles" do you? I think there'll be some kind of relational notion surviving to "bind" collections. Maybe there'll be a revival of the "concept" I dunno. Or you may be right, but I don't see the "powers that be" investing the promotional whizbangs on a track-by-track basis; I think some "collectional notion" will persist. But maybe not for indies. It's pretty exciting, what's happened to the recording & distribution of music over the past 10 years. My kid's band has been together since high school, have recorded & distributed a couple of CDs and pressed an LP (same material as one of the CDs). All on their own, no real adult intervention. Now if they'd only listen when I tell 'em "it's supposed to MAKE money, not COST money...."
