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.
I guess, haha. Not like we care all that much, though, if it's good music, that's all that matters. When I listened to the song you posted, I was reminded of YUKI, although they're quite a bit different. YUKI has more arrangements and incorporates more instruments into her songs. Also, her voice is a bit weird, being very nasal, but I really love it, makes her have a very unique tone.
True, I don't care where from or from what time-period. I usually also separate the artist from the art. And sometimes even the lyrics from the song :) Yuki sounds interesting indeed. Gonna need to re-hear later this day :)
