Album Cover Art Quiz

Weasels Ripped My Flesh is a great album.

Anyone else notice they got this one wrong? It should the M.O.I. but they count it as Z himself instead.
I'm up to 30 right. Been at it all day wracking my brain. I haven't given up yet because there are at least 3 or 4 more I recognize but still haven't placed...MY BRAIN HURTS!

EDIT: OK, reached 41 and finally gave up. I also admit to googling about the last 10 bands because I was sure it was them but couldn't think of the album name. At least I had the bands right!
There was one I never got that I was sure I knew, but when I gave up and checked the rest of the answers, it was a band I don't remember ever hearing, so I must have had the picture confused with another album. Of the 13 I missed, I can't say I had a shot at any of them because they were all bands I never listened to (and in the case of a couple, I admit I never even heard of), though several of the ones I got were also bands I never listened to (of the 54, I only liked 30 of these bands at any point in my life; I like far fewer of them now), but I remembered most of the album covers vividly.
Fun quiz, Hou-Dat! How did you find this?
