In reply to Christina Aguilera.

I agree, but you have to admit that Madonna's theme was like NONE others. The depth of the lyrics, the metaphysical questioning of the purpose of her loving, even the mention of Sigmund Freud separated this theme from the rest by light years. I'm still impressed by how successful it was, even though it was so experimental and it came from her flop "American Life" era, in which at that time she was publicly scrutinized for being anti-American. That song is a thought-provoking masterpiece.
