I'm not sure I understand what your point is, that since digital discovery doesn't provide every single artist in perpetuity throughout the universe that it is somehow not useful as an avenue of discovery?

I can spin this argument directly around and guarantee that if you go to the Louisiana music factory in New Orleans, that for every artist and album they know about, there are 1000 international or country specific artists that are available only online to listeners in America via online channels.
