Its greatest part is obviously the chorus melody. Even without Ozzy singing it. Noel found those perfect chords and sings some gibberish that sounds nice. After those two bright spots, the disc rapidly falls apart. Disc Two is a daunting task laying before its listener.
Every song is weighed down by a massive wall of guitars and bass playing the same thing.
There are no interesting musical segments or even mildly interesting tones or timbres. The band is absolutely bereft of any musical imagination. The will it takes to put a second disc of this crap in one's CD player is unbelievable. And by the middle of the disc, one has probably stopped listening. The sounds just numb the brain.
