Any good anime shows similar to "K-ON!"?

[<3Japan]

I just got done watching the Japanese show called "K-ON!" and I really liked it, but it was only 13 episodes. *Sadface*
Do you know of any other anime shows that are really similar to it?

Thanks in advance.

Thanks a lot PauZai! I'll definitely check those out!
Thank you GekiDan and c0oL_sEi for the suggestions!

Wow Its hard to find a similar one cause K-On was unique and good. I try to suggest:

Bamboo Blade
Hidamari Sketch
Kamichu
Nogizaka Haruka no Himitsu
Kimi Ni Todoke

Well, K-On is a music related anime so Beck would be a good anime to contemplate K-On.
