discogs_genre — Discogs artist-genre and artist-style affiliations (2015)

Description

Two bipartite networks of musical artists and the genres or styles of their releases, from the Discogs database. Discogs (discogs.com) is a user-built online database of music recordings, whose contributors catalog releases (albums, singles, compilations, etc.) together with their credits, and classify each release into one or more of 15 broad genres (e.g. Rock, Electronic, Jazz) and, optionally, into finer styles (e.g. Deep House, Free Jazz, Punk); its content is published as monthly XML dumps. These networks are built from the releases dump of 1 October 2015, which contains the 6,379,659 releases accepted in the database at that time (drafts and the few rejected or deleted releases of the dump are excluded). Nodes are artists and genres (genre) or styles (style), and an undirected edge connects an artist to a genre or style if the artist is credited in at least one release of that genre or style, weighted by the number of such releases. An artist is credited in a release either as one of its main artists or with a release-wide credit (e.g. producer, mixer, or performer on all tracks); credits limited to individual tracks are not included.

genre: artists and genres.
style: artists and styles.

Artists are identified by their Discogs id, and their names are the Discogs names, which include a numeric suffix (e.g. "John Smith (2)") to distinguish artists with the same name. Discogs uses placeholder artists such as "Various" (for compilations) and "Unknown Artist", which are kept as nodes. Artists without any release with a genre (or style) are not included in the corresponding network.

The networks have the following properties:

(Node) is_artist: whether the node is an artist (otherwise it is a genre or style).
(Node) name: the name of the artist, genre or style.
(Node) discogs_id: the Discogs id of the artist (-1 for genres and styles).
(Edge) count: the number of releases of that genre or style in which the artist is credited.
(Edge) first_year and last_year: the earliest and latest release years among them (-1 if none of them has a known year; the years are as entered in Discogs, and a few are evidently mistyped).
