A good collection of Dio songs! Some highlights for me were Holy Diver, Don't Talk to Strangers, Rock n' Roll Children, Hungry for Heaven, Sacred Heart, and Dream Evil.
Some complaints: I didn't like the live recordings of the songs that much (although I do love the studio versions of Last in Line and Sacred Heart). Also, they should replace the last two tracks with All the Fools Sailed Away and Lock Up the Wolves!
