** Here's a rule of thumb: 35% of videos uploaded have some relation to VideoGame/{{Touhou}} since the characters are memetically famous, 25% are related to Music/{{Vocaloid}}, 25% have some relation to any current anime (this can include official uploads), and the rest is just everything else, ranging from covers to manga uploads to music uploads [[SeriousBusiness that may end up getting banned]] and forced to listen to the replacement song. There is, of course, [[{{Crossover}} overlap between these categories]].
