I think that comparing voices is a bit rude. So, what if a voice sound similar to another? Does it mean it can't be used? I bet she wanted to let you down.
She once said Aline sounds like the lovechild of Midori, Tei and Camila, and in the Nicovideo spam incident, she said Aline sounded like a mix between Camila and Siana (or Siena Kotone, I think, which is a completely different UTAUloid, but in her *cough* perfection, she wouldn't notice that she spelled it wrong).
I had to stand her hatefest everyday before just simply blocking her (you know, spamming videos other people made with Aline wasn't cool in my book), so, I know what I mean.
