Whitesnake's "Slip Of The Tongue" is just as good as "1987"? Haven't heard it.
AC/DC's "Flick Of The Switch" is just as good as "Back In Black"? Haven't heard it.
"Adrenalize" by Def Leppard kicks ass and is really underrated? HELL NO. This is easily my least favourite album of theirs. The gig I went to was good though.
Glenn Hughes isn't all that great and easily the worst non-Ozzy Sabbath singer? (sorry Spiff!) Yep. I'm just going by the performances with Sabbath, though - he was all doped up when he did the album. His solo stuff rules though.
"Judgement Day" by Whitesnake should be called "We love Led Zeppelin, especially the song Kashmir"? Dunno, haven't heard it. "Judgement Day" by Iron Maiden sounds nothing like Led Zep, though, so I don't know what you're talking about.
"Rock & Roll Over" by Kiss is much better than "Destroyer"? Yep.
Pantera's best album is "Projects In The Jungle"? Haven't heard it.
WASP's "The Headless Children" is better than "The Crimson Idol"? Definitely.
That the first WASP album is even better than both of them? Nup.
That's a lot of "haven't heard it"s. Hmm.
