Although the overlap seems to point in that direction (and also the fact that I do enjoy the Witcher books and games very much) it’s rather coincidental:

I actually prefer fully acapella, white-voice songs (but I do enjoy instrumental ones too) And regarding leather I’m more into making gear like chokers, cuffs and whatnot (though I’m not trying to make any money out of it as I don’t sell)

I like traditional slavic folk music and leatherworking (which is misleading what I do is more like crafting rather basic things out of leather, I don’t tan or work the leather myself)
