I've taken a likening to listening to neofolk while playing Dark Souls and Bloodborne. Metal or hardcore is a bit too distracting for me to play something like those games while appreciating both at the same time. A lot of neofolk really fits well with the atmosphere of those games, the dark, melancholy, distinctly European feel, often with strange imagery. Something like Death in June, Current 93, Nature and Organisation, Forseti, Vali or Neun Welten.
