Fantasy is my #1; I will give almost anything a chance if it has strong fantasy elements. Post apocalyptic, superhero, alternate history, science fantasy, some supernatural, romance, and a few fandoms (especially Game of Thrones) are also likely to catch my eye.
I have a lot of anime songs I like. I'll just spam a bunch of them like some of the others in this thread. To all those on mobile or with slow connections: I apologize for nothing, enjoy the painfully slow page loading time with so many embedded Youtube videos.
