Note:  There are some groups in which a "Best Of" or "Greatest Hits" album will get you all you need to have.  This is not one such act.  If you must, So Far and the 2005 Greatest Hits have their most known songs on them, but you want to go much deeper than that.  Until the record company releases a box set, I would strongly recommend buying the first four albums.
