Gordon said: local traditional is always the most popular
This is not the case in Japan, Korea, China and I am sure others. The vast majority listen to Western pop and locally produced pop in Western style. Psy is not a phenom only here. :)
Gordon said: Why do We not learn their music styles?
This is one of my questions. Our classical and their classical both take years of study to play well. They have elected to learn our classical and have superb practitioners. There are amazing pianists and violinists in particular coming from the East. Why does Western classical have such appeal for them?
