Believe it or not, one of the best ways to find out about a country is listen to songs written about it. You may have heard of Vietnam before, but probably you haven't had the chance to visit it or you may still consider it a country of war. Personally, I believe songs have the power of a cultural embassador that can take you to a faraway country and enable you to understand its people.

So, why don't you try listening to some Vietnamese songs (both folk and modern songs)? I'm sure you'll discover some very beautiful things about Vietnam. Here are some great Vietnamese music websites:

2. http://nhacso.net/Music/ (Vietnamese)

And some categories of music in Vietnam (according to nhacso.net):

5. 'Không lời' = Songs without words

Have fun.
