Somebody went to a lot of trouble to make it appear the characters of Sesame Street were jamming out a heavy metal song by Slayer.
Is this copyright infringement? Should it be?
From the stupid point of view, the video creator is plagiarizing both Slayer and Sesame Street, and obviously should go to jail and be fined a million dollars.
And this is why the old way of copyright needs to go away. I think any ordinary person can see the value--no matter how trivial or flippant--added by this masterpiece of video editing.
