"Aniara" is a song by the American metal band Unearth. The song is essentially based on a Swedish epic science fiction poem by Harry Martinson, also titled "Aniara." The poem details the journey of a spacecraft named Aniara, which is carrying a vast number of people from a dying Earth to Mars. However, due to a miscalculation, the ship is thrown off course and becomes permanently lost in space. The song follows a similar concept and tells the despairing story of the passengers on board the Aniara. As they drift further away from their destination, they begin to lose hope and their sanity. The lyrics depict their despair, feelings of isolation, and the futility of their situation. The chorus of the song speaks of the passengers' longing for home and their struggle to find meaning in their seemingly endless journey through space. It portrays a sense of desperation and the realization that their lives are forever changed. Overall, "Aniara" explores themes of isolation, despair, and the human struggle for purpose and hope in the face of a seemingly hopeless situation.
