This first rap song math video is great however, I'm not sure whether or not the song in the background is something that the teacher created on something like garage band but if it's not she is definitely breaking copyright because she does not site the song at all. If she created it herself then there is nothing stopping her from posting this on the internet!!!



The second movie the "Do You Know Movie" uses a song in the background that it never sites and it uses at least six minutes of it. I can imagine that that in probably more that 10% of the song or else the song would have to be over an hour long. Second it never sites where it received the information it was putting forth.
