Classical Rock Fan-made Vocaloid A mixture of these/other
This is a rather broad question with rather limited answers. There's more to liking a song than just its genre, so I find myself listening to loads of different types.
Fan-made
Imma throw this out right here: Kancolle arranges are on a whole 'nother level. If I had to pick a single category to listen to for an eternity, it'd hafta be that.
