I didn't like it at the clip, and I was so weirded out during the first listen just because the intro is so different than I thought it would be because of the clip *laughs*
But I have to admit, after a couple of replays I do like the song. I also love how smooth the dance is(and Maachan's mistake...<3 I caught it the first time because I noticed her scurrying), compared to the jumpy Brainstorming. Kimi Sae Ireba and Brainstorming work really well together, because they are so different. Brainstorming hit me as awesome right away and I love listening to it, while Kimi Sae Ireba takes more listens but I do agree it's one I can sing to and it sticks in my head a bit more.
I also like how Riho is THE ACE in Brainstorming, while Reina is THE ACE in Kimi Sae Ireba and in the opposite song they both take a bit of a step back so it's obvious, while the line distribution is still pretty kicking.
I'm severly satisfied and I really want to hear E-cha the most of the b-sides... gah I'm already planning out which ones I will get '
