YouTube always listens. Now whether they are able to do something about it, that's a different issue. With these copyright complaint issues, no other website deals with such a volume of consumers, creators, and rights-holders. The gears may turn slowly but they do turn.
I look forward to musicians/writers to be more flexible with revenue. I don't spend hours on a video just so they can get 100% of the ad revenue if I were to use their song.
