Discogs label–genre
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 a
label and a genre. An edge indicates that the label was involved in the
production of a release of this genre. The left nodes represent labels and the
right nodes represent genres.
