An article on appropriation and copyright that has a long list of comments that are worth reading just to see the ocean of different understandings that exist around the copyright space.
"Musical instruments produce sounds. Composers produce music. Musical instruments reproduce music. Tape recorders, radios, disc players, etc., reproduce sound. A device such as a wind-up music box produces sound and reproduces music. A phonograph in the hands of a hip hop/scratch artist who plays a record like an electronic washboard with a phonographic needle as a plectrum, produces sounds which are unique and not reproduced - the record player becomes a musical instrument. A sampler, in essence a recording, transforming instrument, is simultaneously a documenting device and a creative device, in effect reducing a distinction manifested by copyright."
"In 1939 a young musician from the Zulu cultural group in South Africa, penned down what came to be the most popular albeit controversial and internationally acclaimed song of the times. Popular because the song somehow found its way into international households via the renowned Disney's Lion King. Controversial because the popularity passage of the song was tainted with illicit and grossly unfair dealings tantamount to theft and dishonest misappropriation of traditional intellectual property, giving rise to a lawsuit that ultimately culminated in the out of court settlement of the case. The lessons to be gained by the world and emanating from this dramatics, all pointed out to the dire need for a reconsideration of measures to be urgently put in place for the safeguarding of cultural intellectual relic such as music and dance."
"As the world becomes increasingly more connected to media, the consumption of music as cultural goods rises as well. It is speculative to assume that this proven increase in quantity will make music a more central part of peoples' lives, but it will certainly attract more scientific attention to the behavior and perception transformations associated with it."
