CatalogDNA

Unlike Spotify Wrapped or Last.fm, which flatter listeners with "people who liked X also liked Y," CatalogDNA tells musicians what their music actually sounds like structurally, even when that contradicts their stated influences. Structural truth over affinity flattery.

The output is a report a musician could otherwise only get from a musicologist, and only after months.

The living demo

Ray recorded music as Le Rug. One of his Le Rug albums is titled Party With Peter Burns, an explicit nod to Pete Burns of Dead or Alive. When CatalogDNA analyzed his four-hundred-track Le Rug catalog, the canonical structural match came back as Pete Burns / Dead or Alive.

The album title says, "I know about Pete Burns." The fingerprint says, "you sound more like him than you thought." The album is a self-aware homage; the fingerprint reveals the influence runs deeper than a title.

The full Le Rug analysis is public at lerugray.github.io/le-rug-musical-dna: 439 tracks across ~15 releases (2007-2020), broken into fingerprints, chord vocabularies, influence comparisons, era-based evolution, and per-album deep dives. Ray's catalog was the original test case for CatalogDNA and still serves as the primary development reference. Content may change as the software is still in development.
