The song "Don't Know Why" by Norah Jones has lyrics that reflect feelings of regret and confusion over not showing up for someone important. The narrator says things like "I waited 'til I saw the sun, I don't know why I didn't come," expressing a sense of sadness and questioning their own actions. The lyrics evoke emotions of longing, melancholy, and a wish for escape, as well as a deep connection with someone who remains on their mind despite the distance or absence ("My heart is drenched in wine, But you'll be on my mind forever").
