I wasn't very happy with S/mileage's music after Yuukarin left, it was trying to accommodate the newbs, but this single is actually pretty enjoyable and may be the one that could re-ignite my love for s/mileage. Let's see how this turns out. I hope they also get some of the promo pie that UFA's been using.
And the newbs seem to have improved, they still need lots of work, but it's encouraging. (they're still far from the 9th and 10th gen girls though)
