As we have all heard countless times (and seem to have to explain once day to someone protesting a band's admission to the site in PP or PR on the grounds that they aren't prog), PP and PR bands are NOT prog. Thus, it seems a contradiction in terms to have a five star rating available for these bands. How can a non-prog album be a masterpiece of PROG?
I can see it being an excellent addition to any prog music collection, as it is related to prog, but it can't be a masterpiece of prog if it's not prog in the first place...
Of course, if we added 4.5 stars (masterpiece of subgenre, but not masterpiece overall), they could be masterpieces of PROG RELATED or masterpieces of PROTO PROG without being actual masterpieces of PROG MUSIC.
But, back on topic, I strongly feel that the "masterpiece of prog" label should be reserved entirely for bands that actually are prog...
Thoughts?
