The year is not quite over, but we know the top selling CD of 2016.
It's not by Beyonce ... but by Mozart.
Billboard reports that 1.25 million CDs in a Mozart box set have been sold.
One clarification: Only a few thousand people bought the Mozart box set.
Billboard counts the different CDs in a box set as separate sales.
So when you put 225 CDs in a box set, the math almost guarantees a smash hit.
