What this proof establishes

This recording was released in 1992, before generative AI. ProofProfile's catalogue derives from the pre-2022 AcousticBrainz and MusicBrainz source corpus, and ISRC is the stable recording-level bridge from that source corpus to the authoritative cc-db-prod track record.

CopyrightChains and Bitcoin OpenTimestamps make the exact committed record independently verifiable today. The cryptographic proof does not by itself establish authorship or ownership of the underlying recording.
