I surprised to see the song choices of what some people hate, but then that is opinion for you. Seeing as this is meant to be your least favourite I'm gonna stick to one choice, and there is genuinely only 3 or 4 Momosu songs I'd consider less than average. I guess my very very bottom track though is Nebou Desu. Date na no ni.... I'm not a fan at all though there are a couple of others that I'm not to fond of either. I was surprised to see how many people hate Rainbow Pink, I can certainly understand why someone else would destest it, but not a Morning Musume fan. Of course it's all opinion but personally I find Rainbow Pink hilarious and I think it's taken a bit too seriously. There's plenty of others I could dispute on how the hell I find it impossible to dislike certain tracks but there you go.
