I knew time and tide would bring things around.  My favorite J-Pop review site began expanding coverage to include more Hello! Project type songs.  Lex just covered Perfume's Chocolate Disco:

"Even though the chorus is really repetitive and the girls just say 'chocolate disco' (it's more like CHOKOREITO DEISUKO) over and over, it's what makes the song so catchy."

Oh, just go listen at YouTube.  If it doesn't get stuck in your head, you're a better person than I.
