K-on! Bring it on!
Love offbeat series like Lucky Star, Azumanga Daioh and Yotsuba&!? Then check out K-on! It follows the foibles of a high school music club (they've just enough people to form a pop band — nevermind some can't play instruments). Filled with lots of quirky, short, often non-sequitur gags, this is the perfect thing for anime/music lovers looking for a laugh.
