You just gotta love a Black Sabbath compilation that starts off with Hole In The Sky. I also like the fact they include one song apiece from Technical Ecstasy ("Back Street Kids")and Never Say Die (the title track). There are some obvious choices, like Iron Man, Paranoid, War PIgs and Black Sabbath, but you can't have a Black Sabbath compilation without them and they also include deeper album cuts like Supernaut and Into The Void. I also like the choices from Heaven and Hell ("Neon Knights"), Mob Rules (the title cut) and Born Again ("Zero The Hero"). 15 songs and not a bad one amongst them. This would be a good introduction to Black Sabbath and it is also good for die-hard Sabbath fans like myself.
