Not by far their best single. Perfume has always had a very unique, cute but classy, playful and intelligent, sound, but here they exhibit something a bit more mundane. I actually like the b-side more than the a-side, though in either case I'd prefer listening to their older works. I haven't got 'Voice' yet, their other single from 2010, because I want to see if the new album will feature the b-side (if it does, I don't want to spend so much money on tracks I'll have only copies of).
