Remix stresses that creative ideas come from combinations of other ideas. Remix suggested that every idea is either a mash-up or a recycled version of an old creation. I am not convinced that these are the only two options for creative works. Does that mean that hip hop culture is not art because it involves sampling from other songs? Absolutely not! Hip hop is just as valid of an art form as any other musical genre even if it does involve sampling. Does it need to involve sampling? I think it can exist without sampling.
Art does not have to be a mash-up or recycled from previous pieces of art. That does not mean that those forms of art or invalid. Combining or tweaking existing art can be a creative expression of an individual. Does the individual who combines or tweaks art needs to be subjected to copyright? I think that if a mash-up can blend songs in a way that makes them unrecognizable than they should not be subjected to copyright but I am unsure if they should be subjected to copyright if they are recognizable. What I do not believe is that the creative works are only composed of mash-ups and recycled versions of old art work. One can be influenced by artists work and use that for their own creations.
