I never really hated any of the songs but playing them a few times definitely gets me singing most of them. They lowered the Hard daily song cost as well it's 15 now I just noticed that.
I already read the Maki diary...I didn't know that was SIF whoops.
One more thing about the UR Kotori...her stats are low...like really low I didn't expect her to be the best since it's free but she feels like eye candy more than a center, then again it's a 100 lvls so what do I know...
