For me its either "Ultimate Sin".....Or....."No Rest For The Wicked".....Like some of you already said each album has some good even killer songs.....but overall they are my least fave of the bunch !!!!
I really don't have a "worst-pick" Ozzy Osbourne album(s) pretty much all of the ones I own/purchased are quite the treasure and have their own individuality Classic uniqueness about them: from the Hard Rocking Debut of Blizzard of Ozz, Diary of A Madman & Bark At the Moon and the Ultimate Sin are my most favorites Hard Rock/Metal Classics then I would say the Ozzman Returnedeth & the new one Black Rain is pretty "solid" Rocking: I do like Wicked Babies but not as much as the ones so mentioned above yet I must admit it does have a nice hefty edge to it. Much respects
The legendary Randy Rhoads is an electric "Crazy Train" Guitarist/Musician to the max!
I cannot stomach any of the Jake E. Lee albums. Not that I think he's a bad player, because he totally rips! But I just think they sound so dated and cheesey.
