It's a very rare thing to have one achievement that no one else will ever match. Michael Jackson has a few, with the most concrete being the highest-selling album in U.S. history. 'Thriller' is the only album to sell over 29 million copies.

But those aware of Jackson's legacy know that it goes beyond numbers. The youngest of the Jackson 5 grew to be a bona fide star in the '80s with Prince being his only rival as a pop artist. The run he and producer Quincy Jones had starting with 1979's Off the Wall to 1987's Bad has been written about and praised hundreds of times and will likely continue dozens of more times into the future.

The singer's fame and place in pop culture is so big that -- even though he was a human being like the rest of us -- it seemed he would somehow live forever. That's partly why nearly everyone was shocked at his 2009 passing and still are, years after his prime.
