I'm a fan of the OST from Mount and Blade: Warband. (this video is in alphabetical order. The main theme starts about halfway through.)

Cool thing about Dracula is that, because it is in the public domain, and because it is told through journal entries, it can be read in the real time of the entries. https://draculadaily.substack.com/ is a newsletter that sends you emails of the particular day's entries if you're into that. It's already well underway though, but could be fun for a reread next year
