Sony Music Group is the American holding company that controls the recording and music publishing business of Japan-based Sony Group Corporation. Established on August 1, 2019, Sony Music Group serves as one of the Big Three major music companies worldwide and represents Sony's consolidated approach to managing its entire music business outside of Japan.

Headquartered in New York City with an additional office in Culver City, California, Sony Music Group operates as the umbrella organization for Sony's two primary music subsidiaries: Sony Music Entertainment (the recording division) and Sony Music Publishing (the publishing division). This consolidation brought together Sony's previously separate recorded music and music publishing operations under a single unified structure.

As the second largest music company in the world after Universal Music Group, Sony Music Group manages and oversees a vast portfolio of musical content, artists, and intellectual property. The company is managed by Sony Entertainment and represents a significant portion of Sony Group Corporation's entertainment business.

The formation of Sony Music Group marked a strategic reorganization for Sony, streamlining its music operations and creating clearer oversight of its global music assets. This consolidation allows for more efficient management of the company's diverse music interests, from artist development and recording to music publishing and licensing across international markets.

Through its subsidiaries, Sony Music Group controls numerous record labels, manages extensive music catalogs, and represents both established superstars and emerging artists across virtually every genre of music, making it a dominant force in the global music industry.
