Apple CEO Steve Jobs celebrated his 55th birthday yesterday.  What also happened that day?  iTunes sold its 10 billionth song.  Greatest birthday gift ever?  Yeah I think so.  Congratulations, Apple.  This is quite the achievement and deserves a top spot among the rest of them.

Fun fact #1: The 10 billionth song download was Johnny Cash’s “Guess Things Happen That Way.”  It was downloaded by Louie Sulcer of Woodstock, Georgia who was granted a $10,000 iTunes gift card for being the one to hit the milestone number.  Also tomorrow (2/26) is Cash’s birthday; he would have been 78 years old.
