They often require you to be very dynamic in both range(often expecting you to use a full, comfortable 2 octave chestvoice range, something many singers don't even have) and power and to have excellent breathing. Of course, Ayumi isn't an excellent singer so she may seem sub-par singing those hard tracks at times.
All her releases since Love Songs had really tough songs among them(Love Songs had Love Song, sending mail, Last Angel, November, do it again, FIVE had progress and BRILLANTE, Party Queen had...actually, most of the songs on Party Queen had hard sections, some songs had VERY low sections, LOVE had Song 4 u, which requires an above average range and strong dynamics and again had some pretty tough sections, too - even You & Me is much harder than it sounds), as did most of her albums before Secret.

lol i don't know why but i love people with knowledge on such things on this forum.
I like that because probably you can be less judgmental or put away your taste a little bit when saying "this sounded HORRIBLE" or "THIS WAS THE BEST SHE EVER DID" kind of thing.
