Read the extensive documentation in the " Classical Extras" page for help in using and configuring the plugin. The “Add cluster as release” plugin is also very useful.
MUSICBRAINZ PICARD ITUNES SCRIPTS INSTALL
I also recommend that you install the " View Script Variables" plugin this enables you to view all the hidden variables that are populated by "Classical Extras": particularly useful if you want to write your own scripts to use these variables, but also helpful sometimes just to understand what has been produced. The latest development version (as well as archived previous versions) is on my github site. There is an officially released version here. Be sure to turn file naming off once you have initially saved the files otherwise Picard will try and rename them again if you save them again and will add a "(1)" at the end. If you rename files, then you can also set the folder name for the album - see my script below: Filenaming: Select the folder to move files to when saving.Either way has downsides, which do not look like being fixed imminently, so it is a matter of personal preference. Also, this option will delete any embedded cover art and replace it with MB's own (if it exists), which can be irritating. However, if you do clear existing tags, be sure to list tags that you do not want cleared or overwritten. If you do not, you may get unexpected results when Picard does not set a tag (thinking it should be blank) but does not delete the existing one. Tags: you may wish to clear existing tags.See the Classical Extras page for details of how all this works. As well as being used for genres, folksonomy tags can be used to flag certain works so that the 'alias name' rather than the standard MusicBrainz name is picked up - this can be very useful to avoid non-Latin script names (or indeed any foreign names). The Classical Extras plugin has specific options for doing this, so it is probably better to untick the “use folksonomy tags as genre” here. They can be used as a proxy for genres (MusicBrainz does not store genres per se). Folksonomy tags are mutipurpose tags that anyone can add to releases or tracks.It is very important to tick "Use release relationships" and "Use track relationships", otherwise the Classical Extras plugin will not work properly. Metadata: See below for recommended main options.General: If you log in (assuming you have registered so that you can edit metadata), you will be more easily able to upload new releases and use your own defined "folksonomy" tags (see below).There are lots of choices, so you need to decide what suits you best.

Picard (free) is the music tagger that accompanies MusicBrainz and is essential if you are going to use MusicBrainz to edit your tags.
