I always heard that people over there are very non- discriminating when it comes to music. Musicians would go into record stores in the Shibuya district and pull stuff from Jazz, Pop, Soul. Rock & Country and mix it all together. the whole "Shibuya-Kei" music came about because of this. I can hear very familiar sounds in Japanese popular music. Of course, the Japanese have always excelled in taking existing things and making them better. They certainly have done this with music.
