There are many,

t-ara - falling U

Bandari-Dream Chaser (Bandari’s light music seems to be acceptable)

Kana Nishino - thinking of you

Sting - Shape Of My Heart

Nana - Lonely

Asan - Always Quiet

Hu Yanbin - Moonlight

It depends on whether you want a male voice or a female voice. I don’t listen to Chinese music very much
