Let's see ... their best albums have average ratings of 4.42, 4.36 and 4.35. I fail to see why that should mean they're overrated.
By the way: How can anything be OVERRATED? Let the people decide ... and they have decided. I don't think that the 5 star reviews by fanboys cause an album to be overrated either, because you quickly get an equal amount of 1 star reviews by people who want to rectify the rating. In fact, this even causes the album to be underrated ((1 + 5) / 2 = 3. If the fanboy had rated it 4 stars, that might not have caused the "countervote").
I think that the current ranking algorithm properly addresses the problems ... Train Of Thought was overrated (top ten), and is now IMO properly rated (not even in the top 100 anymore).
Octavarium is currently at position 29, and it is likely to drop further (because I think that I agree with the public opinion that it is a 4 star album, and the average rating should settle somewhere around 3.9-4.0).
