I'm 41 and am not bothered by the term cisgender or by gender nonconformity. The assumption that gender fluidity is a Millennial construct, and not endemic to the human condition, is totally bass-ackwards. I think some of y'all watch too much cable news.
I associate Candy D. with smooth, pop-jazz, and sort of a bastardization of her father's music with De Perikels (and later). Kelly is a bit more of a traditionalist than that, although she does traffic in some very populist moves and histrionics that are probably designed to sell records.
