Like, I know where you're coming from Picaflor, but Ayu is just so diverse as it is... I've always thought of her as being 10 different artist in one throughout the past 12 years she's been active. She's done so many different genres, and yes, she does stick to pop tunes/rock songs/ballads mostly but.. still.
This video made me see this fact a whole lot clearer!:
