K-On! (2009–2010)

This show is nothing short of a masterpiece. Only a genius could write a story that leaves such character attachment. After a few episodes you will find yourself strangely attached to the light music club, and all its members. The brilliance of the character development, each one with their own little quirks and traits, is the strong point of this show. Though each episode is pretty devoid of any real plot, on a per-episode basis, the pacing is great and it never becomes dull.

If you love music, you'll love this show. The opening theme, Cagayake Girls, and one of the songs used during the series, "Fuwa Fuwa Time", are catchy as hell. You'll find yourself downloading the mp3s and putting them on your iPod, or what have you.

The first episode might not hook you, but if you watch 3 or 4 then you will surely become a fan.

Best part? There is a second season, and it's even better.
