I’m incredibly obsessed with finding the right aesthetic for my campaigns. Naturally, music is an important part of that and I hand-tailor it obsessively, often having one singular track ready for a specific location.
As such, I made a master list of vague rpg settings mixed with certain aesthetics and wrote down 3 soundtrack sources for these. Those have a more or less similar style and should be a great source to mine music from.
Of course, there are often more fitting sources than three but I wanted to keep it short for now! I might extend those lists and add more genres or remove a soundtrack source here and there but so far I think it covers most things where a session could take place.
