Where Are Ü Now by Justin Bieber is a compelling exploration of longing, heartbreak, and unfulfilled expectations. The song poignantly addresses the feelings of abandonment and yearning for someone who is no longer present in one's life. Key themes include emotional vulnerability, the search for support and understanding, and the struggles of dealing with absence in relationships. Particularly poignant moments in the song are encapsulated in the chorus where Bieber repeatedly asks 'Where are you now that I need you?' This refrain effectively captures the essence of isolation and the desperate need for companionship and reassurance.
