Well, as usual, I'm going against the grain here
I'm a huge fan of critics. I love going to Amazon.com and checking out the ratings. I also search for personal ratings/reviews of certain albums I'm interested in buying. I like asking "what do you think about this album or that album?" and hearing the different opinions. How do you think I found out about Opeth? I did a search on Yahoo for "best melodic death", and it led me to Opeth. I know Opeth is not death, but that's how it happened. I found out about Demoncy by doing a search on "best black metal", "top 10 best black metal albums" and the like. I'm subscribed to dozens of personal album rating pages. Since these people keep up-to-date on releases, the information can come to me. Amazon.com is my favorite - I do a search for Dimmu Borgir, for example, and it gives me a list of what other customers that have bought Dimmu Borgir have also bought. I also love their "listmania" feature (that's how I found out about Immortal, Dissection, and some other bands). Well, that's it.
Now, that's not to say that because one critic thinks a band is junk I won't go ahead and buy the album anyway. For example, COF. I like this band, and no critic can ever tell me how much they suck, because I don't think so, and that's all that matters.
I also get Promethian Crusade. This magazine is chock-full of reviews of bands I've never even heard of. If the review sounds interesting, I'll try out the band. Usually it's right on the money.
