Actually I don't believe any of the other artists mentioned COULD actually do it. For one, they are not dancers. You need to be classically trained. Even Madonna said how hard it was to learn the Tango! Neither do any of them possess her unavoidable sexiness and air of mystique. A combination of sexiness, boldness but subtle naivety are required for this part. The others may be considered sexy by some, but none has that brilliant combination that makes Madonna so alluring. She was perfect in this part. Her voice was magnificent and it was a travesty she was not rewarded with an Oscar. I am. It knocking the other artists but I genuinely believe none of them could be so convincing. They are limited!
