Lyric discussion by shadowwiththeeyes 

This is the so-called "Hungarian Suicide Song". It was written by 2 Hungarian composers, and is about the dead girlfriend of one of them (read the lyrics, it seems pretty obvious it's about a dead lover). After the song wsa recorded, it supposedly resulted in suicides all over Hungary (including that of one of the composers) and was banned there. That's when a bunch of American singers covered the song. This is about the most famous version, probably because Billie Holiday is one of the few people who had a voice that could capture the mood and feeling of the song. This also is supposed to have caused suicides all over America, and got banned there too.
