Damn, YouTube, who are all these people? Are any of them named Darren Aaronofsky or Geoff Barrow? I don't give a shit if they are, but that would be awesome if they had watched it.
I don't think there's any evidence that I could hurt any of the copyright holders financially, and sizable evidence that mashups, fan fic, etc, only increases the value of the referenced products, in much the same way that press coverage does. The artists involved may or may not like it, depending on their taste, but once your baby is born, you have no right to censor what other people say about her. This is a form of cultural criticism, however cheeky or referential, and however pitiful or tiny.
Here's one that slipped through the cracks. The song is me, Evan, and Sean. It's almost entirely stolen. I made the music out of samples, noticeably Johnny Rivers and U2. The video is from the movie "CQ", directed by Roman Coppola. The lyrics refence James Bond and Indiana Jones at length. I don't know why it hasn't gotten busted, I'm guessing because it's too transformative for the bots to catch it. I think the simple act of juxtaposition is transformative but, let me tell you amigos, YOU CANNOT ARGUE WITH A ROBOT.
