Lol YES. Well, I guess it would generally be songs that have inspired me while creating Malleus Maleficarum. So lots of Yuki Kajiura, Kalafina and many others! Here are some key songs to name a few:
Can't find the original version of Aura, but here's a version where the uploader has lowered the pitch. It doesn't have much to do with my story in its early stages, but I would say it's pretty relevant later on when fleshing out the villans.
Always though Kimi no Gin no Niwa would've been a cute ED for the first part of Malleus Maleficarum, hehe...
There's also Promised Land by Risa Shimizu. My favourite lines especially are "You're my destiny" and "You're not my heaven, nor my friend." <3
