CR06

There were several aspects of the movie we viewed in class that interested me.  I never realized how many songs that I love to listen to (for example, Led Zeppelin) are based on songs from the past.  Although this portrays musicians in an unoriginal light, one thing that I observe is that there are only so many notes in music; they haven't explicitly copied the exact song from the past, they only touched on a piece of it to assist their creation.  Another point I found highly interesting was the fact that writers are able to include anything they want in their work, regardless if it is their personal idea or not.  All they have to do if they borrow someone else's idea is simply cite it.  Why is it perfectly legal for writers to engage in this, but illegal for anyone who tries to include movies or music not of their own creation?
