The ListenBrainz team is currently working to create Playlist support and we've chosen JSPF as our playlist transport format. This format will be used for importing/exporting playlists, in our API and internally between our web servers and the client browser sessions.

There are a number of fields that we require that are not part of JSPF/XSPF, so we've defined two extensions to JSPF. Our proposed format example is here:

   "playlist" : {
      "extension" : {
         "https://musicbrainz.org/doc/jspf#playlist" : {
            "created_for" : "Mr_Monkey",
            "collaborators" : [
            "copied_from" : "https://listenbrainz.org/playlist/9dae92c5-c98e-4e7e-9c15-8b6d32607aed",
            "public" : "true",
            "last_modified_at": "2020-11-27T10:45:49+00:00"
      "creator" : "ListenBrainz Troi",
      "date" : "2005-01-08T17:10:47-05:00",
      "title" : "1980s flashback jams",
      "track" : [
            "title" : "Gold",
            "identifier" : "https://musicbrainz.org/recording/e8f9b188-f819-4e43-ab0f-4bd26ce9ff56",
            "creator" : "Spandau Ballet",
            "extension" : {
               "https://musicbrainz.org/doc/jspf#track" : {
                  "added_by" : "zas",
                  "artist_identifier" : [
                  "added_at" : "2020-11-27T10:45:49+00:00",
                  "release_identifier" : "https://musicbrainz.org/release/8d3acbb4-c541-4324-a124-a670615f0f77"
            "album" : "True"
      "identifier" : "https://listenbrainz.org/playlist/7f4cf4d3-f5ca-453a-b5c8-00e8a30a9bac"


The https://musicbrainz.org/doc/jspf#playlist namespace defines the following fields that augment the data about a playlist:

  • created_for: Which ListenBrainz user was the playlist generated for? This is for music recommendation bots generating playlists for users.
  • collaborators: Who are the ListenBrainz users who have access to edit this playlist?
  • copied_from: This field identifies a playlist, using the identifier syntax, from which this playlist was copied from.
  • public: Indicates if this playlist is public or private. Must contain the value "true" or "false".
  • last_modified_at: The timestamp for when this playlist was last modified.


The https://musicbrainz.org/doc/jspf#track namespace defines the following fields that augment the data about a particular track:

  • added_by: The ListenBrainz user who added this track.
  • artist_identifiers: A list of MusicBrainz Artist URIs that identify the artist that are part of the MusicBrainz artist credit id for this track.
  • added_at: The timestamp for when this track was added to the playlist.
  • release_identifier: The MusicBrainz ID URI for the release that contained this track.
