Mycelia was Imogen Heap's blueprint for paid music metadata

The system

Mycelia is a research and advocacy project founded by musician Imogen Heap, describing itself on its own site as 'a research and development hub for music makers.' It predates the current wave of generative AI: Heap began the project to address a narrower but related problem, that recorded music circulates with too little reliable metadata about who made it and who should be paid. Mycelia's stated mission, in its own words, is 'to empower a fair, sustainable and vibrant music industry ecosystem' and 'to unlock the huge potential for creators and their music related metadata so an entirely new commercial marketplace may flourish.'

What the documents establish

The clearest artefact Mycelia's own site describes is the Creative Passport, defined there as 'the digital container to hold verified profile information, IDs, acknowledgments, works, business partners and payment mechanisms, to help get music makers and their works, linked and open (data) for business.' A related project, Life of a Song, is described as dissecting Heap's own track 'Hide and Seek' to show how metadata and rights actually move through the industry. Independent BBC reporting from 2018 corroborates the project's aim, describing Mycelia as a 'think and do tank of music professionals set up by London-based artist Imogen Heap' that 'argues that having a verified global registry of artists and their works would help make the payment process more transparent.' Neither source claims Mycelia's metadata format became an industry-wide standard; the BBC piece places it alongside other, separately branded efforts of the period, such as the blockchain platform Choon.

Craft and rights

For a musician, Mycelia's underlying argument is that a recording is only as valuable, in payment terms, as the metadata travelling with it. A file that reaches a streaming service or a training dataset without a verified credit for every writer, performer and rights holder cannot easily route payment back to them, which is the same provenance gap AI training has since made more urgent. Mycelia's prototype answer, a portable, artist-controlled identity and rights container, is a plausible shape for that fix, but it remains a proposal and demonstration project rather than infrastructure any major platform has committed to running on at scale.

Outcomes and open questions

Neither source establishes whether the Creative Passport or Life of a Song format was adopted beyond Mycelia's own pilots, or how the project's ideas map onto newer, AI-specific provenance standards, such as C2PA content credentials, that have emerged since.

• Has any streaming or distribution platform adopted a Creative Passport-style verified artist registry in production?
• How does Mycelia's rights-and-payment metadata model compare with newer, AI-specific credentialing standards?
• What became of the Creative Passport and Life of a Song prototypes after their initial pilot period?

Mycelia is best read as an early, artist-led diagnosis of the metadata problem that AI training has since made unavoidable, not as a settled answer to it.
