Structs

A recording is an entity in MusicBrainz which can be linked to tracks on releases. Each track must always be associated with a single recording, but a recording can be linked to any number of tracks. A recording represents distinct audio that has been used to produce at least one released track through copying or mastering. A recording itself is never produced solely through copying or mastering. Generally, the audio represented by a recording corresponds to the audio at a stage in the production process before any final mastering but after any editing or mixing.
