Rate Your Music (or RYM) is an online collaborative metadata database of musical and non-musical releases and films which can be cataloged, rated and reviewed by users.
ATTENTION! THERE'S AN UPDATED LIST OF THIS ARTICLE HERE.
I am a very heavy user of this website (HERE's my profile) as I really like to catalogue and have a minimum of control of what I listen to and RYM allows me to have that.
The main idea of the website is to allow the users to add albums, EPs, singles, videos and bootlegs to the database and to rate them. The rating system uses a scale of minimum a half-star (or 0.5 points) to maximum five stars (or 5 points). In this manner, Rate Your Music bears resemblance to a Wiki, as all of the databases content is generated jointly by the registered user community (artists, releases, biographies, etc); however, the majority of new, edited content must be approved by a moderator to prevent virtual vandalism.
As they have a massive amount of users and RYM's charts are the most faithfull I've seen and far away from being biased or snob in any kind.
Because of that I thought about doing a special article with the 100 top Prog Rock albums of all time, according to the website. Of course that this ratings may change as new users vote to albums, but as for now I think is a VERY interesting list.
Almost all the albums have more than 1.000 ratings which makes this list very solid, and differently than Progarchives, for exemple, reviews doesn't have any weight, so albums that are not reviewed don't get lost along the way, which is a better way of doing things. To understand how they calculate their ratings please take a look HERE.
More info about RYM on Wikipedia HERE, or create your own profile and start using the website HERE.
I'll divide this article into parts, 15 albums each, and in the final the top 10. I'll also put a song of each album that's considered to be their best or simply my favorite ones.
PS. Of course that every day that goes by the ratings change a bit, but the overall result will take some time to change. Maybe in one year I'll re-visit this list and update it.
