"Car Window" is a song by Thomas Headon about a young man, stuck at a red light, who notices a girl in the car window opposite him who keeps staring at him. He wonders if she loves him and how he will ever know. He admits that she's cute, but also thinks that maybe she finds him strange. Over time, he becomes obsessed with the idea of her, even though he doesn't know her name. He daydreams about her writing a song about him, but ultimately resigns himself to the fact that she's probably far away now that the light has changed. The song captures the fleeting nature of attraction and crushes, as well as the feeling of wanting to know if someone feels the same way about you but not having the courage to find out. Overall, it's a catchy, relatable song that many listeners may be able to identify with.
