Of the "oldies" I liked Manpower the best, and The Peace was also nice. The one I like the least is I WISH, it's still a borefest (not as bad as the original, but I will almost always skip it)
Of the newer ones (updated without Reina and a few arrangements), I liked Wakuteka the best, it sounds much better than the original, Sakura and Riho made a great work out of it. I specially love the part after the instrumental break, around 4:00
One Two Three also sounds great, I actually like Ayumi in here and the added voice processing doesn't bother me the least. This is the defining song of this rebirth, of this "Colorful Era" and is imho, Morning Musume's best song ever. Maybe the original was a tad better, but this updated one is also good, it was already an almost perfect song, so...
Renai Hunter is the one where I missed Risa/Reina the most, their voices were great for this song...
Wolf Boy is awesome. I didn't quite get it at first (like many Tsunku songs), but after a while it sticks. Damn I wanted it to have a PV so bad... I hope we see its choreo soon on a Hello Station snippet of the MM concert or something...
Anyway, it's an enjoyable album. I was prepared to be dissapointed, but I'm liking it a lot. I only wish it had "casual" videos of them dancing to most/all of the songs like C-ute did. I believe it's a missed opportunity. Oh, well... Maybe for next time
