E=MC2 should be #1 on that list. HC however is one of the best albums ever released. People will appreciate that piece of art in few years from now. "Give It 2 Me" , "Candy Shop", "Miles away" , "Beat Goes On", "Devil", "She's Not me" are all classics.

People with poor taste can't instantly process its brilliance and feel the effort behind it. The only problem is that this was Madonna's weakest era promotion wise and that's why it's extremely underrated.
