How do I prove my music is human-made?

Why this question exists now

Detector-driven enforcement creates a new failure mode: human-made music flagged as AI. Vendor accuracy claims lack public validation (see the detectors answer), platforms act on those detectors anyway, and the burden of proof lands on the artist. Separately, copyright registration now asks about AI involvement, and contests increasingly verify what their rules require.

The evidence hierarchy, practically

• Process artifacts — DAW project files with edit history, stems, takes, MIDI. The single strongest category: generation tools don't produce believable session archaeology.
• Version trail — dated drafts and exports. Cloud storage timestamps and versioning give you this for free if you let them.
• Performance evidence — video of takes, live performances of the material, session photos.
• Registration and distribution records — dated deposits establish when your version existed.

The pattern: evidence created during creation beats anything assembled after a dispute starts.

What's coming, honestly

Content-provenance standards (cryptographic signing of media at creation) exist for images and are moving toward audio; the industry's voluntary AI labels (July 2026) are declaration, not verification — nobody audits them yet. Until a real provenance layer ships in music tools, the boring answer stands: keep your project files, and if a platform flags you wrongly, dispute it with the making, not with an argument.
