As to me, I absolutely
adore Ayu's rock and pop-rock stuff. At the same time I really like her electro stuff (including NEXT LEVEL) and most of her ballads... Not even so - I do LOVE Ayumi's ballads, they're her brand, and I'm never tired of them
And if I'd say, that I want Ayu to make more pop-rock (smth like superiorly beautiful Decision, talkin' 2 myself, is this LOVE?, Microphone, etc.) I'm sure many AHS'ers would like to kill me brutally and without remorse
This all is a matter of
favor. Ayumi's music doesn't become worse, imho, it's just changing and evolving. That's much better than a monotonous singing machine, isn't it?
