Top 20 Albums of All Time (to Americans)

My boyfriend sent me this link to an interesting blog post, in which a guy used the following mathematical formula to determine the Top 20 Albums of All Time.

He based his ranking on sales, resales value, critical review and Grammy wins and came up with the following list. Please note that NOT ONE SINGLE ONE of these albums was produced after 1991, providing more support for my theory that everything written after I graduated from UGA the first time stinks.
