Why this pair

This is a pair from a dispute where no infringement was found. Public background: 8-note ostinato; Jury for plaintiffs 2019; set aside 2020; 9th Cir. affirmed 2022 (Gray v. Hudson). Sonalize's scores are measurements, not a view on any dispute.

How this was measured

Compared from the full recordings; Sonalize's fingerprint lookup confirmed both songs. The same engine runs in the Sonalize app on your own device. A score measures how alike two recordings are; it isn't a finding about copying, legal advice, or a rights clearance.
