How it works

From catalog entry to royalty review

  1. 01

    Create a catalog

    Create a catalog for a musician and keep its Notes ID for future requests.

  2. 02

    Add songs

    Import songs by identifier, then add each Notes song ID and musician ID to the catalog.

  3. 03

    Review the catalog

    Notes reviews new songs in the background and refreshes the catalog on a rolling 30-day cycle.

  4. 04

    Use the results

    Read a catalog summary or full review data, then show the useful next step in your product.

What Notes checks

Clear signals without exposing private review methods

Registration gaps

Signals that a song or recording may be missing from a relevant royalty source.

Ownership gaps

Signals that a share may be unclaimed or not represented as expected.

Identity gaps

Missing or conflicting identifiers that can make it harder to match a musician to a song.

Recording gaps

Signals that a recording and its songwriting information may not connect correctly.
