K-On!! Season2 ep1-9 Short Reviews (+ Extras)

Before getting into the groove of the reviews, here are my thoughts of the OP n ED of K-On!! Season 2:

OP "GO! GO! MANIAC"

The song is a total chaos at 1st, but once u get use to it, its kinda okay. The 1st time K-On!! ep1 was aired, many people from Nico Nico Douga & Otakus (+me... once) complained that its like Hirasawa Yui(Toyosaki Aki) singing crap in a chipmunk voice. But after a few eps, i found it quite cute! By the way, only "Maniac" person like Yui can sing "GO! GO! MANIAC" while playing the guitar.

ED "Listen!!"

Great choice on clothings, nice song, nice ED, but I don't like it. Why? I don't really know. Guess i'm used to "Don't Say Lazy" as K-On!'s ED. (1 more thing, I LOVEx1000 YUI's LOOK IN "LISTEN!!" Its better than "Don't Say Lazy" Ver. Yui, let me Kidnap you!!)
-AniToBaka gives: C+

Extra: "Pure Pure Heart"

OMG, I LOVE IT!!! The 1st n 2nd time I listen to it, I almost burst into tears. I kinda felt "grief&Sadness" when listening to it!
