For me, it's normal, that the newest songs I like less than the old ones, because I have some memories connected to previous ones. But I think, that after a month time I will enjoy listening to (miss)understood album as much as - for instance -Duty. All in all, I cannot say there's any bad Ayu song. They are all different, and I do not agree with people claiming they are the same. Maybe they just don't listen to them carefully enough to hear the difference?
