Taking a stab at what could have been the source of misunderstanding (because it sounds like you guys weren't even talking about the same thing)...
Zunu's comment ("At this point it's pretty clear C-ute's manager is kicking all kinds of ass.") sounded like a it was taking about C-ute recent success in general rather than how those cover previews look, and apparently you only meant to talk about the covers (?). I mean, if you were or at least interpreted to be talking about their success in general then, even though it's obvious management plays a HUGE role, you could see how there is incentive to give the girls some credit.
Anyway, I watched the Kanashiki Amefuri performance again because the song is amazing, and I actually have come to like the dance (esp. at the beginning and during instrumental breaks) a lot now. I love the group so much. I really want Chisato to stop being styled to look so old though.
Reallyyyyyyyyyyy hoping we'll get PVs soon. Since this comes out a week after S/mileage's single, I thought we'd get something a week after we got the PV for Yatteruchan.
