It kind of depens on how well you can own a style.
Ayu jumped from this genre to that since the very beginning of her career. It shouldn't surprise us she's doing it again. It's like with NEXT LEVEL or Party Queen, aka the fact she's trying new stuff doens't mean she's going to drop ballads and rock pieces.
Did she EVER drop ballads and rock pieces before? Nope. Did she change countless times? Yep.
Basically because she's trying, not really changing.
Imo she's one of those singers whom can give their soul to every song (mostly because they take part in choosing the songs).
