pop (not good one, if you ask me)
6. Memorial address -
excellent, classic J-pop

rock

a mixture of everything, but unlike RAINBOW, this time it works for me

dark again, but in a (much) lesser quality compared to Duty

circus

ballad
14. FIVE -
classic J-pop, somehow
15. Party Queen -
a mixture of everything, again (I really can't put my hands on these things), but somehow feels not as pleasant
16. LOVE again - the
ballad-feel really stands out here for some reason
(I still found out new things about ayu and her albums as I wrote that) (Amazing)
