Ayu and "eeeeeeeee"s

[SheFliesHigher]

I think Ayu is a reasonably talented vocalist. Over time, she has become much more versatile. But she has always seemed to have trouble delivering high "eeeeee" notes. Especially on My Story, she keeps hitting those terrible notes that prevent me from turning my volume up too loud. For example, in the choruses of My Name's WOMEN (...kantan ni nakanai shIIIIII) HAPPY ENDING (anata ga inaIIIII) and CAROLS (ShiroIIIIII yuki...)

I really think Ayu should work on singing these notes more gently, or at least stretch out sounds different than "eeee"! I mean, she could do "ooo", "aaaa", any of those other lovely vowels.
