That's so cool! I actually prefer this Italian version of the themesong over the original version by Momoiro Clover Z, mainly because I dislike Momoclo, I just dislike Japanese idol groups in general (especially female idols) because many of them lack singing talent compared to actual musicians and music artists, and many of the Japanese idols and idol groups I've heard are horrible live, which is why so many of them usually lip sync at concerts and "live" performances instead of actually singing live. It has bothered me for many years that these less talented idols and idol groups are so famous in Japan and they monopolize the Japanese music industry, virtually always over-shadowing all the actual musicians and artists who actually have real singing and musical talents. And Momoclo IMO is one of the worst female idol groups I've heard, their vocals are mediocre at best and they are much worse live. so I was never keen to the fact that they sang 'Moon Pride' for Crystal, if Toei wanted an actual decent idol group to sing the themesong, I would've preferred Morning Musume, at least they are better singers & performers than Momoclo.
Anyway, enough bashing of Momoclo and Japanese idol groups from me and going back to the topic of the Italian version, I actually love it and I think the vocals in the Italian version are much better, cleaner and sharper with more range. Even though I do think the Italian vocals perhaps sound a bit too "mature" for this type of popish and upbeat bubblegum pop song, but whoever the singers are who sang the Italian version clearly have better singing & vocal skills and range than Momoclo.
