The remix graph Suno sealed

When one Suno track descends from another, that lineage is written into its metadata: extension chains, "edited from", "covered from". It should be the most interesting social graph in AI music. But on nearly every public endpoint, Suno replaces those pointers with a string of all-zero UUIDs (00000000-…-000000000000) — you learn a source exists, but never which clip it was.

A few places forgot to redact. We used those gaps to record every edge that fell through, and assembled a cross-author remix graph. This report is not about how large that graph could grow. Its 2024 core — a one-time backfill — is sealed for good: the alias route whose serializer skipped redaction is gone, and the playlist object it pointed at redacts almost everything when read directly. What remains is one narrow gap Suno still hasn't closed, adding an edge every few weeks at most.

The edges come in kinds. The vast majority are extension chains — the internal relationships as a single song is lengthened segment by segment. The true remix gestures — edited from and covered from — are rarer, 15 in all, but they are the social act of one person building on another's work.

This graph did not accrete gradually. It is the sum of one backfill, mostly sealed leaks, and one that still drips. Here is where each edge came from, and the current state of that tap:

Put the three channels together and the conclusion is mostly settled: two of them can never add another edge, and the third adds one only rarely. This is not a young dataset that will fill in — it is a near-sealed archive, overwhelmingly a one-time slice of history with a slow drip on top. That is exactly what makes it rare: as far as we know no one else holds the same graph, and Suno has closed nearly every way to collect more of it.

Even inside this sealed archive, the telling asymmetry holds. Among the leaked edges, the child — the clip that did the remixing — almost always resolves to a public creator. The source it remixed — the parent — almost never does. Across all 107 edges, the number of sources we can publicly name is:

But even an anonymous source leaves a shape. Take the source clip below: its identity is redacted, yet our records prove that 2 different public creators each built work from it. That is the silhouette of a cross-author remix hub — we can see the spokes even when the center is dark.

Here are the nameable remix tracks we recorded — each declaring a (redacted) source of its own. This list is nearly fixed: it can only lengthen through the one live gap still open above.

These edges are also browsable one clip at a time: open any clip in the single-clip lineage explorer to trace its parents and descendants through this near-sealed archive. The cross-author network no longer has a standalone page of its own — it is too small, and grows by at most a handful of edges a year through the one gap that remains.

In July 2026 we went back to the 97 distinct source clips these edges point at and asked Suno's public API what became of each. The answer is a portrait of an archive going dark: only 6 are still public. 80 have been turned private, and 11 have been deleted outright.

Chasing those pointers to the end, only 4 creator-to-creator pairs can still be confirmed at the handle level. Three of them trace back to Flosstradamus's Soundclash contest source clips (the Master and Drums stems producers were invited to flip) — all publicly nameable: flosstradamus → jpichardo, imess, and mazta. The fourth is alejosimaginaryband → alejopastran. Every other source is private or deleted, so we leave it unnamed.

That darkening is only half the picture — the graph is not entirely static. On 2026-07-27 we audited every clip on Suno's two live editorial shelves (44 clips) for the same redacted fields. edited_clip_id came back fully scrubbed (24 of 24 zeroed) and concat_history too (2 of 2), but cover_clip_id was a real UUID on 3 of the 20 clips that carried one — including a pointer we resolved all the way to a named creator. That single field is the entire live tap left: 5 edges recorded this way (2026-07-05 to 2026-08-21), against 102 sealed in the original 2026-05-10 backfill.
