i think the title sounds fine.. it'd maybe sound more refined if it were just "Aitai na" but this is Hello! Project. i'm pretty sure the word "refined" has been banned from their entire enterprise.
It sounds like a Nishino Kana, BENI, Juju, Shibuya-Gal title. Not that that's a bad thing, I love me some Shibuya-Gal type music. That'd actually be a pretty cool direction for C-ute to go in since their getting a little older and stuff.
And lezzbereal: Tsunku gets pretty good momentum going and somehow he fucks it up. I hope it's not with a C-ute single though.
Oh, I liked the other singles. I just didn't love them. I tend to love more intense songs, like Iza Susume! Steady go!, OK YEAH, Renai Hunter, 123, Kiss Me Aishiteru, Heroine ni Narou ka, etc, etc.
I would be happy if it sounded like Kimi wa Jitensha Watashi wa Densha de Kitaku, tbh. (btw what are we calling that single so no one has to type it out? )
