Major publishers are large, well-established companies in the music industry that handle the publishing rights for a vast catalog of songs. These publishers manage song registration, licensing, and royalty collection on behalf of songwriters and composers. Major publishers often have extensive networks and resources to promote and exploit music across various media and markets. They negotiate deals, track song usage, and ensure that creators receive compensation for their work. Notable examples of major publishers include Universal Music Publishing Group, Sony Music Publishing, and Warner Chappell Music.
