I like it a lot, but compared to recent singles like Resonant Blue and Onna ni Sachi Are... it's not quite there, imho. Though I am a sucker for those "corny techno sounds" kingthaking was talking about. Haha.
And so far, my ears are picking up A LOT of Taka/Reina... so line distribution looks not so even again. I heard a couple of the other girls (like Risa, specifically)... eh. They could still do better in that department.
All in all, for me it's a good song. Not great, but good.
