As the title says....which song still haunts you emotionally? And why? A (freely accessible) link might greatly bring your point across.
Mine would be: (Typhoon - "Empiricist") https://www.youtube.com/watch?v=9E328pIZWFM
The lyrics go deep and it just touches me. No otherwise special attachment.

Heard a long distance dedication on live radio by the late Casey Casem back when he was still doing America's Top 40. I still think it was my Ex fiance who sent it. She knew i listened to that show. looking back im not sure it was really her but it wrecked me to even hear this song for years after that.
