As Juliekspon the origin of this way of saying is Coleridge-The rime of the Ancient Mariner....Albatrosses were considered a emblem of hope, and in some cases the soul of dead sailors....in the Rime a sailor kills an albatross, and brings bad luck to the ship. So he is forced to carry the dead albatross around his neck...
So this became the symbol of carrying a burden for something bad you may have done....in this song, the burden is just a stressful life, and they say that you should let the albatross-weight go, to be happier.
