I absolutely loved this song, I personally feel it's her best work. The video was astoundingly glitzy. Many amateurs in the music industry wanted to know how Cher had her voice altered like that and some credited flanging for it but her voice technique was not flanging like disc jockeys like Howard Stern used but because of "Autotune" a special vocal range expander that many rap stars adopted after hearing this song.
I guess David Bowie forgot David Gilmour was 1 year old when he was born. Maybe his brain was addled from all that Khat Iman was bringing in from Somalia.
