Right brain is activated by music,art,emotion,and feelings.

Left brain is activated by words, calculation, and analysis.

Maybe Jpn people prefer words to melody when they listen to enka

But I have read an newspaper article which says Japanese people listen to Enka by left brain though the Japanese also listens to the classical music by a right brain.

Enka is Japanese traditional style ballad.

For me, enka is very ( maybe most ) emotional compared to other genre of Japanese songs. So I do not understand why enka stimulates the left part of brain.
 
But possible explanation is this: Japanese people mainly listen to the words ( lyrics ) of enka, not the melody. Therefore left brain is activated.
 
I wonder which part of brain of non-Japansese people get activated when they listen to enka.
 
Maybe it depends on how well they understand Japanese.
