Description

Rating is a new feature which has been introduced with the server release of November 23th, 2008.

It allows users to rate MusicBrainz entities (artists, labels, releases and tracks).

Each user rating is a number between 1 and 5. Then the system aggregate users ratings to compute the average community rating.

By default community rating is shown. As soon as user rates an entity, he/she will only see his/her own rating.

Display of ratings can be disabled in User Preferences for those who prefer not to use or see ratings.
