Of all the recent anime announcements, none sounds as bad as
K-ON! (Keion!). But relax. I don't mean... Naruto-bad, or
[insert-most-hated-anime]-bad, just tone-deaf-bad. Because otherwise this looks like a highly lolicious anime, about
4 girls trying to save their school's music club; despite being total noobs at playing musical instruments or reading music.

Originally an amusing (and amusical) 4-koma manga by kakifly, K-ON! has been serialized in the Manga Time Kirara magazine since 2007, with
one single volume compiled so far. By the way, the title K-ON stands for Kei (light) Ongaku (music) - thanks
MyAnimeList.
No other details about the anime are available at this time, but you can bet I'll be keeping my eyes open. Aye, just my eyes, cause my ears are no good, either.
