i hadnt heard much of sabbath until i got this cd in a store for seven bucks. and thats the best seven dollar cd i ever got. this cd opens with hole in the sky (4/5), probly one of the best opening tracks ever, then its goes from a soft and great acoustic riff of Dont Start(too late) into the heavy intro of Symptom of the Universe(5/5) which may soften later in the song a little but its just ozzy at his best and tony iommi as well, with a great solo in there. Megalomania (4.75/5) starts slow then gets heavy, this ones almost as great as symptom. the rest of the songs are still good, but not like the first four. the original cd, which i have, ends on Am I Going Insane? and i feel like im going insane that a song like thats on and ending an album like that. its not a bad song, it just doesnt fit in on here. i strongly suggest buying this one if you like sabbath or ozzy.
