There has been so much controversy about the recent inclusion of The Beatles in the forum. The thing is, amongst their discography, only "Abbey Road" could be considered as proto-prog (maybe also "Sgt. Pepper's" as the first conceptual album). Obvioulsy, the rest of their output is pop music.
But let's think about many bands that edited a few prog or prog-related albums and then changed to pop or pop-rock music (Genesis, Gentle Giant, Yes... lots of bands). Nobody complains in those cases, because of the great importance of their first albums. It seems the problem only comes when a pop-rock band edits a prog album.
I think only prog, proto-prog or prog-related albums from every band should be included in the archives, after all that's the music style we all look for when we check this webpage. Also, that way it would be easier to review some albums. For example, "Invisible touch" is a one star album is you consider it prog, but it might deserve something better as a pop-rock album. Finally, we would not have to see albums like "With the Beatles" review here, which I think is absurd (and I think it is what's getting many people on their nerves...)
In some cases it would be difficult to decide which albums are prog and which are not, but for me it makes no sense to include POP records in Progarchives, no matter if they are from The Beatles or from Genesis.
