Yes, I know that "Iron Man" has been edited for this particular compilation, but that doesn't mean that the entire album is terrible. If you're just cutting your teeth on Black Sabbath, "Greatest Hits 1970-1978" is a great place to start. Not only does it include tunes easily recognized by casual listeners ("War Pigs," "Paranoid," "Changes," and the aforementioned "Iron Man"), it also includes great tracks that don't get as much airplay like "Children of the Grave," "Dirty Women" and "Sweet Leaf."
In my neck of the woods, the only version of "NIB" that you'll here is the Ozzy/Primus recording, so I was also glad to see Sabbath's original version included here.
Hardcore Sabbath fans will definitely be upset with the edited version of "Iron Man," but for casual listeners or people who are just discovering Sabbath, this is an excellent disc to purchase. It's relatively cheap and opens the door for the purchase of more Black Sabbath albums. Recommended to new fans and curious passers-by.
