Guitar lesson videos removed from Youtube

A guitar lesson videos of a teacher were removed from YouTube, because a recording company didn't like the fact that he taught people how to play rolling stones. This copyright business is really going bad. Tomorrow you might have a record company copywriting all the ragas. And maybe a couple of years later, you'll have a copyright on each and every note of music. Imagine the situation if 7 different companies own the copyright for 7 different notes.
