I'd disagree with this song being "not coherent" and whether Sakura's lines fit; I think everything comes together nicely despite the clash of elements such as the harsh electronics playing over the strings, and I think Sakura comes in at just the right time. That said, I do share a similar sentiment in that I loved the previous two singles a lot more than this one (and I'm not really feeling the leopard print motif either), though I still really like this one.
And hey, it's great to see some old fans come back into the fold for this song.
As far as the video is concerned, I'm willing to give it a delayed "thumbs up" after careful deliberation. The whole "fake city background with flashing everywhere" thing may seem lazy at first, but the subtle things are what makes this video work: the way the cities come alive when the chorus hits, the quick "Morning Musume" lightning flash that appears for a split second...and damn, I love that symbolic phoenix, a very appropriate image to bring up for this group.
Wow, that Riho/Sakura song really does sound awkward at first!
But for the most part I really like it...I'm easily swayed by these kinds of funky beats.
Here's a preview of the Eripon/Zukki/Masaki/Haruka b-side:
It kinda reminds me of Pyoco Pyoco Ultra a bit. I like how prominent Zukki sounds on this, but overall it's just an okay song.
