Boiling down a decade's worth of great albums into one list is exceedingly hard.  Coming up with a Top 10 list is just about impossible.  As you'll see in the list below, ranking these albums was too much for me.  I chose these albums by looking at the star ratings I gave to all the 2000-2009 albums in my collection.  These came out on top.
