Brightness and density are scored against this record's own sections, not against music in general — they say how its parts differ from each other, and nothing about how it compares to anything else.

Separated into parts by a source-separation model, so each lane is the instrument it names.

Every moment against every other. Squares on the diagonal are sections; a bright patch off it is the record recognising itself — the second chorus meeting the first.

Measured from the YouTube master on . Section labels describe how the energy of the recording moves, not its musical form — a machine can see loudness climb and jump, it cannot hear a chorus arrive. Anything we were not confident enough to state is left out rather than shown with a caveat.
