I watched 'Everything is a remix' from part1 to part 3 once again because it was such a good video. To summarize, part 1 is about history of copying music. There are a few examples, of which the most well-known one is Led Zeppline. Part 2 deals with copying movies. There are a number of interesting examples including Star Wars. I was a bit shocked that Star wars copy that much movies in the past. The third one suggests how new ideas are made. In most cases inventions come from the old one. By copying, changing and mixing, new products are invented.
There was part 4 and I tried to watch it as well, but failed because it takes as much as 15 minutes.
In Korean music society, there has been many cases that one artist copy other's. Some people even argue that over one third of K-pop song copy the oversea singers' one up to some point. In part 3, the video-maker claims that there's nothing really new. Every new ideas stem from old one, and by mixing and developing it, the brilliant ideas are made. However, still we need to protect the copyright of foreign singers. The new ideas are result of the artists' hard work, and new products are not as competitive as the replica. Without protection of the new idea, people will no longer be willing to think creative idea.
Then how about movies? Should we regulate the copying of certain movie scene from old movie? It can be controversioal but I think the movie-maker pays enough fee to old -movie-maker. Still, each movie scene is the own idea.
