I listen to music from all over the world. I believe you can understand a culture through its music. I like especially the old and traditional music, since it can better capture the pure essence of that race or culture. When I need to cheer up, I find that traditional north Thai music is  huge inspiration to hot summer nights, mostly perhaps because their climate all year around is very hot, but I can feel it is appropriate to listen to thai music on a hot and humid midsummer evening. The Lao, Khmer (Cambodian) people also have similar music, maybe because the Khmer empire used to cover all these countries in ancient times.
