There are quite a few parts of this that feel a bit mainstream catchy. I am getting tired of Tsunku's chant obsession/repetition. For me personally he always takes it just one or two times too much. I really like a lot of the places this song goes, however. Can't wait for a slightly clearer version so I can start attempting to pick out line distribution.

I think with the wider line distribution that happens in this era, it's kinda exciting to see who got which parts.
I certainly won't be able to go to the serial event this time around. And I didn't have enough money to catch the box set pre-orders (unless they magically do another wave, but they've already done three so I don't think I'll be that lucky ~_~ frickin' love box set boxes as well) so looks like I'll have to be banking on my tickets coming through to see Sayu one final time. I paid for the Osaka one, but it hasn't been sent to me yet, which worries me ~_~ BUT I DIGRESS.
I assume that Sayu's will also be EDM, with maybe a Platinum twist, because her voice suits it so well, but I'm really excited to hear where Mikaeri Bijin will take us.
I'm also really curious to see if the musical style shifts again. It seems to do that with changes in line-ups, they might explore what genres sound good with the other girls' voices.
