What you describe sounds alot like YouTube. 12 years ago, some friends of mine were doing their entire home music playback with a playlist of stolen music uploads. I'd even go as far and claim that YT Music wouldn't exist if people were not trained that YouTube has all the music content they are looking for.

And then there are channels like "Netzkino" who have around a million subscribers and a few thousand full movies online. The claim is all that content is supposedly legal. Well, maybe. But it doesn't look like it...
