Well the only shows I would consider some form of comedy are Fireball, Ika Musume and that high school boys thing. One of those is only 5 minutes long and also ends this week.
Having funny bits of an episode or an occasional less-than-serious (bath house)
episode doesn't automatically make an entire series a comedy.
The playlist will always ebb and flow with what is currently available to air at any given time and it won't always appeal to everyone but I for one find the current list to be overall of a high quality and contain a good mix of genres. Greggums does his job well.
