Si Rehab es a su alegato a la vida, entonces Back In Black era todo lo contrario; el lamento perpetuo a sus errores pasados, el fracaso y la muerte tanto física como emocional. El fin de un amor es también la conclusión de un capítulo en su vida por lo que Winehouse decide componerse un ominoso réquiem y cantarlo con murria y resolución. Porque ella entiende que nada muere del todo, sino se transforma en algo mejor y perdura en el recuerdo a lo largo del tiempo en los momentos que fueron felices.
He left no time to regret Kept his dick wet With his same old safe bet Me and my head high And my tears dry Get on without my guy You went back to what you knew So far removed from all that we went through And I tread a troubled track My odds are stacked I'll go back to black We only said good-bye with words I died a hundred times You go back to her And I go back to..... I go back to us I love you much It's not enough You love blow and I love puff And life is like a pipe And I'm a tiny penny rolling up the walls inside We only said goodbye with words I died a hundred times You go back to her And I go back to Black, black, black, black, black, black, black, I go back to I go back to We only said good-bye with words I died a hundred times You go back to her And I go back to We only said good-bye with words I died a hundred times You go back to her And I go back to black
