I'm a big fan of the gothic rock and everything related with it for about 11 years or even more
But for the last 5 years I was listening to Touhou OSTS, many doujin projects (e.g. Dark PHOENiX, Cool&Create, Ryu-5150, Yuuhei Satelite, etc.) and Len'en OSTs. That's pretty soothing
From gothic rock I can advise The sisters of mercy, Ghost Dance, Mors Syphylytica, Die Verbannten Kinder Evas, 45 Grave, Baroque Bordello, Little Nemo. Yeah, there're different kinds of gothic here - ethereal, post-pink with new wave (idk how to call it) and classical first wave gothic rock.
That's my point this topic is rather needful. Even people connecting to such serious themes often listen to something. So they can find out new brands and it sounds well
