I like jap girls singing
I like it when they scream or moan for mercy during their song lol (sorry that sounds pervy)
I like it when their song almost sonds like a lulaby (sometimes)

music artists I have tried that fit my criteria:

Perfume
Ami suzuki
capsule
GO!GO!7188
Mass of the fermenting dregs
SAWA
Dazzle Vision
michi
nami tamaki
do as infinity
