I am from the U.S. but my ethnicity is Vietnamese so I will recommend Vietnamese songs I really love! :) Vietnamese music are mainly ballads and love songs (very poetic too!) and it has only been in recent years that the music industry has shifted to more pop and western like sounds (as opposed to the traditional music). There are some strong influences of K-pop in V-pop as well.
