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.
The absolutely achingly long build up invokes such strong tension and vivid mental imagery of the end of some fantastical world, the end of a story. And then the final chorus hits like a truck: the final, thunderous cry of a world at its end. Then all is stripped away and you're left with a half-broken voice singing the same refrain, and it's truly over.
Porter Robinson is a musical storytelling genius!
