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.
Spider in the snow by Dismemberment Plan. It's a song about not really getting close to anyone and watching your life go by. Why? Because I probably have seen myself in it a few times in my life.
Hey man, this is dark....
It can be, but I think the song is more meant to be a wake up call to anyone in that situation. It took me a long time to realize it, but kinda is what makes me occasionally come back to it. Would heavily recommend the Emergency and Me album, kinda stands the test of time.
