How about the term "artist" as opposed to "performer"? An artist creates. These so-called divas are nothing more than highly-trained performers. The equivalent of a solo guitar-wanker. Technically flawless, unmatchable skills, spitting out notes without any consideration as to what they are trying to convey.
I saw Celine Dion perform "You Shook Me All Night Long" by AC/DC a few nights ago and was absolutley revolted.
