I often hear the story that sales representatives sing a schmaltzy Japanese ballad(Enka-song) in order to try to win their favor.
I think that it is based on a hypothesise that power generation that can control money is likely to like Enka-songs.
But I also think that this picture of "Enka-songs is equal to old men" is corrupting now.
If anything, the hypothesise has been just an illusion for the first time.
Because I am an old man, and I believe that I cannot move anything whenever I hear an Enka-song.
-----
Of course, some people like Enka-songs, others like animation songs in their childhood. And the other like idol singers or groups of their days.
However, if I were enforced to sing Enka or idol songs at the business entertainment, it is going to corrupt.
These business operations need individual strict data analysis, based on a private information.
For the case of a macro marketing, the big data analysis is going to be effective weapons, but for the case of a micro marketing, it is going to be in vain.

Anyway, I have no relationship between the above story and me, because I am far from money and power.
