K-on! just aired a couple week ago with 5 ep out so far. Yes, it is a anime, but there is a reason why I made a post here then one in the anime thread. Well, Most of all crazy obsessed anime lover out there (including me) are pretty much going crazy over this one anime. People are so crazy about it, The opening and ending theme song to this anime is one of the top selling song in Japan right now. So, it's really more about the music than the anime itself.
