http://en.wikipedia.org/wiki/Saudade There are also less upsetting styles of fado, like smoking mood, or drinking mood fado,
literary "fado for smoking", in a sense of contemplating while smoking, when one mustn't allow ones thought to last
longer then a single puff exhaled....
It is actually very oriental in nature
The upsetting one is also refereed as fado triste "the sad fado", but the word it self doesn't have synonyms in any living languages but Welsh.
