Requiem for a Dream (Remix)
I am hearing a song which is a remix of the theme from Requiem for a Dream. The license claims to be copyleft. Is the artist allowed to do to use this license? Is that legal? He/she is doing more than just a bit of sampling in this case. Is it really recommendable that my students use this?
Here is an article from ARS Technica that testifies to the changing face of copyright and IP.
