Discogs artist–style
Discogs (short for "discographies") is a large online music database that
provides information about audio records including information about artists,
labels and release details. Each edge of this bipartite network connects an
artist and a style. An edge indicates that the artist was involved in the
production of a release of the style. Releases can have multiple styles. The
left nodes represent artists and the right nodes represent styles.
