Rate Your Music is a metadata database where musical albums, EPs, singles, videos, and bootlegs are rated and reviewed by users. This data is then used to generate music recommendations for users and to create rated lists of music albums. Weighted averages are used to calculate the ordering for these lists; regular members who write reviews and rate more albums have a greater weight applied to their ratings. It is a wiki in the sense that users can add, edit and remove content; however, the majority of new, edited content must be approved by a moderator. [Wikipedia]
