What this proof establishes

This recording was released in 2022. ProofProfile's artist catalogue derives from the pre-2022 AcousticBrainz and MusicBrainz source corpus, and this recording entered the record through cc-db-prod's ISRC-linked registration. Its provenance rests on the dates stated above rather than on the era of that source corpus.

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.
