Two of my favorite Sabbath songs are The Writ and Megalomania. Also, really, really love Hole in the Sky, Symptom of the Universe and The Thrill of It All. So yeah, Am I Going Insane and the twisted instrumental (forget its title right now) are pretty weak, but those other five songs are so brilliant Sabotage is my favorite, though it's a near tie with Paranoid. Funny enough, Iron Man is not a favorite at all and Rat Salad is rather silly, but everything else is brilliant. I love Fairies Wear Boots and Hand of Doom.
Sabbath Bloody Sabbath is great most of the way through, and it has a crisper, cleaner sound, which works for the album, but I'm thankful they followed it up with the heavier Sabotage. Vol. 4 is great, but it does have some weird filler. But the songs that are brilliant are really brilliant. Their first album I could probably rank higher, but for me at least, it's pretty overplayed.
Of these six, my least favorite is Master of Reality. I know it seems universally loved, but more than half the album comes across as rather tedious. Sweet Leaf is great though. And I do like Technical Ecstasy, though it has a lot of mediocre hard rock tunes, and Never Say Die is pretty awful, apart from the title track. I've only listened to the new one with Ozzy a few times and it's okay, better than Never Say Die, but not up there with their best, and obviously I just haven't listened to it enough to say anything about it.
