Is Anyone Truly Original?

In Lawrence Lessig's TED Talk on laws that choke creativity he discusses the copyright laws that prevent modern artists to use online content to create new works. However works that use part of the content of copyrighted works are illegal and can be removed from websites. This is questionable because someone who remixes a song is not trying to pass the original song off as their own but use the inspiration and content of the original work and alter it to make it their own. This has been happening since the beginning of time. Artists always received inspiration for their works based on other content they have experience. Some works may be based off an original but it is impossible to that the original was not based off of something else. It is unfair for artists to create works with someone else's content and not credit the artist that they were inspired by. For example Vanilla Ice sampled part of Queen and David Bowie's Under Pressure for his song Ice Ice Baby and did not give credit to the original artists. That was unfair to Queen and Bowie as they worked hard to come up with that catchy guitar tune just to have it stolen. However they probably used some other artists work to inspire theres. No work is truly an original. Today copyright laws and websites prevent works from being published if they use a piece of another artists work. It seems like this is a new occurrence but has been happening forever only now it is able to be regulated. Artists should give credit where credit is due but still be able to create new content based on other's work.
