For years I thought this song was about dying because of the words "It's hard to die". The song was translated from Belgian and maybe something was lost through that process. I was very surprised to find out this song is actually about ending a love relationship and dying to that relationship. The words go on to say "Now that the spring is in the air, Pretty girls are everywhere, Think of me and I'll be there", so it does refer to going on and not actually dying.
It's funny you think you know a thing and to find out later it is the exact opposite to what you thought it was.
