Ok, we are all familiar with the argument "oh, prog-related doesn't mean progressive rock, it's just influences and minor details and such". Ok, most of us agree to this point. The entire section is filled up with bands that we are either totaly convinced they are prog, or completly unconvinced as to their single mention in a Progressive Rock database.
On my behalf, I can say that I agree with the "genre" and most of its acts. However, seeing, as stated above, that "prog-related doesn't mean progressive rock", then why, regardless of their value as music pieces, do we have Prog-Related albums in the Top 100/250/500? In my view, only strictly progressive rock album ratings should be accounted for the rankings, which do more than indulge our Prog rivalries - they are a source of information and recomendation to outsiders. Sure, there are no PR albums in the first 40, but we can find several starting from nº 41 on, starting with Deep Purple's "Made in Japan".
What are your thoughts on this? We can all agree that there are PR albums we might enjoy more than full-blown classic Prog-Albums. But should they count in a list that clearly states in its title "TOP 100 Progressive Music Albums"?
