This is interesting indeed, one possible scenario will be the re-inventing of the labels' role in music, they might become "tour" merchants instead of record distributors, etc. For instance, REM wants to tour in support of their new CD, they sub-out the label for tour logistics and distribution of physical media, once they're no longer using physical media the label's role stays as tour logistics support. Using the labels this way will streamline the music pipeline, get more money into the artists hands, make music more affordable to the masses, allow the artist more control over material. Now, if they would just keep releasing physical media, us media dinosaurs will be content.
