This little known cd is very generous with its twenty songs that are truly Johnny Cash's greatest hits. One may find some of the songs on one greatest hits cd and some on another cd, but this is the first time they are all together. It contains more than all of the hits one would expect to find along with some lesser known songs, so pop this cd into your cd player and learn them all. And as an added bonus, there is a biography of Mr. Cash in the cover.
