How does anyone call "the best song ever"? It's impossible, it depends on shifting moods, tastes, times. There are so many superlative tracks of music in the world and so many more to discover, but all the same, under the classic "put a gun to my head" situation your humble servant chooses this one. No singer has ever touched me as deeply as Brel does. This is my favourite Brel song. End of story.
