Notes:

[1] (1,2)

Taken from the earliest release in the release group.

[2]

Used when uncertain whether composer or lyricist.

[3] (1,2)

This is populated by LastFMPlus plugin and not by stock Picard.

[4] (1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18)

This is not able to be populated by stock Picard. It may be used and populated by certain plugins.

[5]

For Picard>=1.3 this indicates a Various Artists album; for Picard<=1.2 this indicates albums with tracks by different artists which is incorrect (e.g.: an original album with a duet with a feat. artist would show as a Compilation). In neither case does this indicate a MusicBrainz Release Group subtype of compilation.

[6]

Release-level license relationship type.

[7]

Recording-level license relationship type.

[8] (1,2)

With “Save iTunes compatible grouping and work” (since Picard>=2.1.0)

[9] (1,2)

From iTunes Metadata Format Specification
