"Omen" by Disclosure (ft. Sam Smith) is a song about realizing the value of a relationship only when it's about to end. The song is about the feeling of regret and the realization that one has not paid attention to the warning signs that were present in the relationship. In the first verse, Sam Smith explains how the person he loves leaving him made him realize that he had taken them for granted. The pre-chorus talks about how the "silver lining" in this situation is that the tears of the person he loves leaving him served as an omen. The chorus highlights how his mind had ruled his heart, and he didn't pay attention to the light in the dark, but now he sees his partner's tears as an omen and is ready to pay attention. In the second verse, Smith talks about how the person he loves is relocating, and he needs them by his side. The outro reinforces the significance of the message conveyed in the chorus, calling the tears of his partner an omen.
