The Grammy nomination rules clearly state: In both voting rounds, Academy members are required to vote based upon quality alone, and not to be influenced by sales, chart performance, personal friendships, regional preferences or company loyalty. The acceptance of gifts is prohibited. Members are urged to vote in a manner that preserves the integrity of the academy. 
My Beautiful Dark Twisted Fantasy currently hold a 94 rating on metacritic, which assigns ratings based on reviews from professional critics. Not only was it the highest reviewed album of the last year, it is one of the highest reviewed albums of all-time. 
"Inevitably, hip-hop records are treated as though they are disposable. 
They are not maximized as product, not to mention as art." 
To ignore My Beautiful Dark Twisted Fantasy and leave it off of the nomination list is not only insulting to hip-hop fans, it is an insult to all musicians that dedicate their live to the art of music. MBDTF is a musical product of the highest caliber as reviewed by virtually every major music critic. Give the music the recognition it deserves. Despite your personal feelings, give Kanye West the credit he is due. Let's make the Grammys about the music this year.
