There are several, so I'll post the most 最近的 one I've found that nearly makes me cry. I was looking for a lullaby and found this instead...it's so beautiful and the lyrics heartbreaking.
"How Can I Help 你 Say Goodbye" 由 Patty Loveless comes to mind,for me,it always makes me cry 或者 at least want to when I hear it..Why? the lyrics..and everything just thinking about what the song is about and what it means,always found this song to be rather beautiful.
