Symphonic has expanded its TransferTrack catalog migration technology with audio delivery from MassiveMusic, the B2B music and technology company owned by Songtradr.
The collaboration was announced on Wednesday (September 16).
It allows Symphonic to pull audio files and metadata out of MassiveMusic‘s catalog infrastructure when a label transfers its releases.
Labels and artists whose catalogs are already available through MassiveMusic will no longer have to track down and upload their own audio files, the company says.
Symphonic announced its patented TransferTrack tool in February 2024 and says it was the first technology of its kind.
The tool lets clients bulk-import eligible releases into SymphonicMS using only a Spotify artist page or release link.
Symphonic says the tool cuts metadata re-entry, consolidates analytics, and helps clients retain stream history and playlist placements where releases are correctly linked by digital service providers.
Until now, clients still had to upload the underlying audio files, and in some cases other assets, before a transferred release could be submitted through SymphonicMS.
MassiveMusic‘s systems now supply that audio as FLAC files, alongside normalized, DDEX-compliant metadata that includes ISRC information.
Where an incoming label’s catalog already sits in MassiveMusic‘s systems, Symphonic says the content arrives structured and ready for distribution.
Symphonic then coordinates delivery and takedowns, which it says helps avoid gaps and protect the playcount history a label has built up.
That continuity also supports a label’s algorithmic visibility and audience reach, according to Symphonic.
The arrangement lowers the operational cost of changing distributors and lets Symphonic onboard new clients faster and at greater scale, the company says.
“TransferTrack was built to give independent labels more freedom to choose the distribution relationship that best supports their business.”

“TransferTrack was built to give independent labels more freedom to choose the distribution relationship that best supports their business,” said Jorge Brea, CEO of Symphonic. “MassiveMusic’s audio delivery capabilities allow us to take that vision further and create a smoother path into Symphonic.
“This is exactly where we want to keep investing: technology that removes operational barriers and gives our clients greater control over their catalogs.”
“MassiveMusic’s role is to make complex music delivery work reliably, no matter how big or small the catalog,” said James Priestley, SVP Global Sales, Licensing and Technology Solutions at MassiveMusic. “Much of the music that labels need to move is already in MassiveMusic’s 180m-track global catalog. Our modular platform allows the streamlining of many backend processes across the music industry, so working with Symphonic was a no-brainer.

“Together, we can make a complicated transition much simpler for the artists and labels involved.”
Songtradr, which acquired creative music agency MassiveMusic in 2021, brought its key B2B businesses together under the MassiveMusic name in June 2025, folding in 7digital‘s global distribution services, Big Sync Music‘s advertising and licensing operation, Musicube‘s AI-driven metadata and search technology, and Resonance Sonic Branding.
Songtradr acquired UK-based 7digital, which supplies licensed tracks and API services to third-party apps, in a USD $23.4 million cash deal in 2023.
The February 2024 rollout that introduced TransferTrack also brought SplitShare, a royalty splits tool, plus what the company called Enhanced Recoupments and a new Marketing Drivers process.
For Symphonic, the MassiveMusic tie-up is the latest in a run of deals and rollouts going back to late 2025.
In November 2025, Symphonic struck a deal with direct-to-fan platform EVEN, and in February 2026 it partnered with SourceAudio on an opt-in marketplace for licensed AI training data.
In March, the Tampa-headquartered firm acquired YouTube monetization platform Distro Nation, bringing the channels of artists including Lindsey Stirling, Good Charlotte, and Switchfoot under its management.
A month later it launched Symphonic NEXT, a catalog financing and acquisitions program that Brea told MBW represents access to over USD $100 million in capital across the company and its investment partners.
In July, Symphonic partnered with Sureel AI, the attribution platform Warner Music Group acquired in June for an undisclosed sum, to let Symphonic clients track how AI models use their work.
That was followed in August by a deal with startup ArtyShield that put tools built to shield recordings and vocals from unauthorized AI use inside SymphonicMS.
Symphonic was founded in 2006 by music producer Jorge Brea and describes itself as 100% independent.
It raised USD $37 million in a January 2022 Series B round led by NewSpring and Ballast Point Ventures.
Its roster and alumni include Bad Bunny, Daddy Yankee, Marshmello, Doechii, Gunna, Ozuna, Sean Paul, Imogen Heap, Jon Batiste, and Tim McGraw.Music Business Worldwide
