First of all, I definitely have stated my preference for a lot of stuff many times over. Even when it was someone I have serious problems with (Dickinson), I actually voted for it repeatedly, because I recognized the greatness and the beauty and I supported it against lesser albums. So I actually rooted for and supported a lot of stuff here, many times over. Not being just negative, IMHO.
However, as of now I'm pissed that a so-so Priest album kicked out Opeth, a band that's completely on a different level in... well, everything. Except for the "pioneer" quality, in which case Sabbath should be winning against Priest, 'cause they're older.
Yes, in case my favourites and the stuff I find to be genuinely great gets eliminated early and it all gets down to predictable lowest common denominators (oh, wow, the only DT album that proceeded was Images and Words? Don't you say!) I tend to go against what annoys me the most, because in general, these all are, like, good albums. Some are even great. But I don't feel the need to vote for something.
Now, for example, for AMOLAD in any round I'd vote aggressively. For Sabbath Bloody Sabbath or Sabotage, for Winter Thrice (which nobody even thought about nominating) or any Opeth album. For Persistence of Time. For various Pain of Salvation albums. For Six Degrees of Inner Turbulence. Maybe even for some of the early speed metal that combines thrash with power metal, like Tales from the Twilight World or Walls of Jericho. For albums of inherent inner quality, voice, uniqueness or for those that actually transcend that metal paradigm (or why in a "greatest album jazz cup" like this albums like The Black Saint and the Sinner Lady or A Love Supreme or even Mahavishnu Orchestra should win and why I would vote against, dunno, Kind of Blue, much as I like that record).
But these are not those albums. And Judas Priest has the most albums up there, even stuff that's really filler-y, like Vengeance, Class or especially British Steel. These albums should have been left in the lower tiers long time ago. Heck, it's completely not my cup of tea, but I'd actually welcome a Darkthrone record somewhere up here instead of another meandering Priest album again (those guys and quality control...).
Yes, the hysterics to which JP, Dio, Rush get their most rabid fans annoys me. The incessant bootlicking about how flawless and awesome they are. Taken in context, they are awesome. They are even unique. They are however hardly flawless. I realize that I actually am more offended by the overratedness of something actually good than something bad or mediocre. I really love both Sgt. Pepper and What's Going On? and I find both to be great, but seeing both as #1 in those Rolling Stone lists, both for dubious and fishy reasons... well, irks me.
I'm annoyed that "Oh, DIO!" meant eliminating all the actually intriguing, personal, original latter-day Ozzy albums that have 100x the spark, the inventiveness, the melodicity, the riffs etc.
Don't want to support it. The albums are often rather equal (in the latter pairing here, anyway). I'm voting against what annoys me more.
Actually no, the same goes for the first pairing as well, sorry, but these are, like, B+ albums at most. If these were the best metal had to offer, well, I wouldn't even lament not being a metalhead at all.
Again, it should be a legit way of voting.
If you want to be annoyed at me for that, feel free to do so.
