@Drostanxxx, oh come on! The whole part sounds totally soprano. It's not that hard to realize that it was done by the help of a computer. Just check the live performances out and please, try to be more realistic, less fanboy.
@huaynacapac357,Do you really think that this "a-a-a-a-a" part sounds natural? Sharon has a mezzo-soprano vocal range, but that "a-a-a-a-a" part sounds so much soprano. The thing that I'm trying to say is, she has a good voice, there is no need to use computers for that.
