[attractive nausea]

^ I think that was not what he/she was saying, everybody can tell the difference between her vocals back then and today. What she/he was saying was that even back then her vocals were far from being perfect/pleasant to hear, so she/he don't know why all of a sudden everyone is praising her old vocals like they were the shit. (i'm talking about 1999-2001 here, those from her peak, her vocals improved a lot after that and it's a huge pleasure to the ears, but i think japanese people in the comment are refering to the evolution days when talking about her vocals)

Also, everyone has different tastes in terms of vocals, to me the deeper her vocals are the better (hello 2008/2009 era) lol
