This page documents a list of parameters you can POST to the release editor to "seed" it. All values are optional unless otherwise stated.

To create a new release:

The MusicBrainz server includes an example which demonstrates seeding: seed-love-bug.html.

Release data

The name of the release. Non-empty string. Required
The MBID of the release group
A disambiguation comment for the release. Non-empty string
Text to place in the releases annotation. Use a <textarea> / multi-line text
The barcode of the release. May be any valid barcode without whitespace
The language of the release. May be any valid ISO 639-2/T code (for example, eng, deu, jpn)
The script of the text on the release. May be any valid ISO 15924 code (for example, Latn, Cyrl)
The status of the release, as defined by MusicBrainz. Possible values: official, promotion, bootleg, pseudo
Ignore if you already specified release_group. The type of the release group, if a release group will be created. Possible values: album, single, ep, compilation, soundtrack, spokenword, interview, audiobook, live, remix, other (this can be specified multiple times to select multiple secondary types, though only one primary type should be specified)
The type of packaging of the release. Possible values: “jewel case”, “slim jewel case”, “digipak”, “cardboard/paper sleeve”, “other”, “keep case”

 Release events

A release can have zero, one or several release events. Each release event is composed of a date and a country. You must specify a positive integer for the x part of the field name to specify which release event referring to. For example: & or & & &
The date of the release event. Each field is an integer
The country of the release event. May be any valid country ISO code (for example, GB, US, FR)

Labels and catalog numbers

Releases may be associated with multiple labels and catalog numbers, so the fields for specifying these is a little different. You must specify a positive integer for the x part of the field name to specify which label/catalog number pair you are referring to. For example: label.0.mbid and label.0.catalog_number

The MBID of the label
The catalog number of this release, for label x
The name of the label. If an MBID is present, this value is ignored

Artist credit

A release may be credited to multiple artists via what is known as an Artist Credit. To specify the artists a release is credited to, you can use the following fields:

The MBID of the artist. If omitted you will be able to either create the artist in the release editor, or search MusicBrainz for this artist
The name of the artist, as credited on the release. Optional, if omitted it will default to the artist’s current name
The name of the artist as it is usually referred too. Optional if you already specified both credited name and MBID
An optional phrase to join this artist with the next artist. For example, you could use “ & ” to join “Calvin” with “Hobbes” to get the final text “Calvin & Hobbes”


As with labels above, there may be multiple mediums and tracklists which themselves may contain multiple tracks, so again you will need to fill in the x and y parameters accordingly. As with others, x and y are 0-indexed. Values for x must be in consecutive order starting with 0; with at least 1 track for each medium.


Any valid medium format name: you can find the possible values in the release editor page’s source code
The position of this medium in the list of mediums. If omitted, it will be inferred from the order of all mediums passed in (which is normally what you want)
The name of medium x (for example "Live & Unreleased")

The name of track y on medium x
The free-form track number of track y on medium x
The MBID of an existing recording in the database which should be associated with track y on medium x
The tracks duration, in MM:SS form or a single integer as milliseconds
Track artist credits

Refer to release artist credit, as track artist credits share the same syntax. Here too you can have z artists (the first being 0 again).


Other data

Specify the content of the edit note. Use a <textarea> / multi-line text
