Now, imagine the scenario comparable to what @bogomipz said above: "no Beatles, Pink Floyd, No Motown, No AC/DC". I'm betting all of us would be a lot more frustrated and irritated than we are right now. Maybe you won't do anything about it. Maybe I won't, either. But it sounds plausible that a lot of people will, whether they switch to a different service, come up with a solution of their own or simply revert to piracy.
