the heck i never heard Ayumi called Britney a product
 Although Hamasaki initially supported the exploitation of her popularity for commercial purposes, saying that it was "necessary that she is viewed as a product",  she eventually opposed Avex's decision to market her as a "product rather than a person".
Ayumi views herself as a product (i think used to)
I remember in the Duty days that in this magazine they called Ayumi "The Britney Spears of Japan"

 and I felt disgusted because Britney is no way close to Ayumi
and now Ayumi is "The Madonna of Japan"
