When I was first getting into Black Sabbath, I was torn between getting all of the first six albums and getting this album. I made the right decision and got all of their albums. IF YOU WANT THE FULL SABBATH EXPERIENCE...GET ALL OF THEIR ALBUMS. This album is just missing too many excelent songs, like "Laguna Sunrise", "Supernaut", "Behind The Wall Of Sleep", "After Forever", "Into The Void", "Wheels of Confusion", "Under the Sun", and countless others. What it comes right down to is that Black Sabbath didn't release any songs that were less than excelent. In order to compile a "Best of Black Sabbath" album, you would end up combining every song from their first six albums. Don't be cheap, buy all of the Sabbath albums.
