2. Liên khúc xa em kỷ niệm: Xa em kỷ niệm, yêu một người, người tình dối gian, xa nhau là hơn, tình trong cơn mưa, gọi thầm tên anh, trở lại phố cũ, biển ru niềm nhớ, người xưa như mộng, yêu

What this proof establishes

This recording was released in 2000, 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.
