What Kanye West Did: Took shots at the Grammy Awards organizers
When He Did It: December 2012
Why It Was So Controversial: Technically, Kanye did this just before the start of 2013. But we're including it here because it carried well into 2013. And it was controversial because Kanye repeatedly took shots at the Grammy Awards organizers for not nominating him in their big categories every year. Kanye has never been one to shy away from calling people out for not recognizing his musical greatness. But he took things to a whole new level by calling out the Grammy organizers.
