I think the single cover look neat. I can't really make out the song in the preview tho, sounds messy lol. Hopefully it will be better when the full version comes out. I still think Hatsuoka Butterfly is their best song so far tho.
Some thoughts on centreship:
Personally I don't mind Meru, but I don't see how she is better than Haruppi really. I don't really see her as better than Kodama performance-wise, & Haruppi is imo vastly better at the variety front. I have to admit thought I haven't seem a lot of HKT's live performances, & it seems many do think Meru is better than Haruppi in performance presences. I don't really mind her getting pushed, but I do think management have the tendency to push too hard, as the are doing right now. I can see a double centre working out for HKT, & double centres seems to have worked quite well for SKE & NMB. Giving HKT double centre wouldn't hurt imo, & can certainly calm down potential hostility between Team Meru & Team Haruppi.
I think there's really three candidates now for future HKT centreship:
Meru: Really good performance-wise. Can work on variety I guess. Favoured by management. Might draw the ire of original Team H fans.
Haruppi: Great variety. Sometimes does seem off in performance tho. Original centre & third overall in single handshake thus far.
Sakura: Most popular (excluding Sasshi) & original Team H members. I guess she's in between the two in both variety & performance lol.
These are my personal thoughts tho. I would love to hear what do you think of it!
