Paraphrasing Emperor Joseph II's comments about Mozart here to talk about this
http://aramajapan.com/aramaexclusive/arama-japan-interviews-songwriter-producer-steven-lee/55861/ Wherein an American composer says this about working in Japan:
"This is impossible in America nowadays because many people in music industry think more chords make songs sound dated.
We (at least some of us) have been talking about differences between J (and k but mostly J-)pop and western pop - royal road chord progressions, etc. This quote was an interesting and blunt statement. J-pop: more chords, western pop: less chords.
Is it true, though? My initial impression is, yes, I feel J-pop melodies travel more.
