I have recently received a collection of CDs containing old jazz recordings reissued on the Marshall Cavendish label. I had long ago ripped my own CDs to FLAC using dbPoweramp v16.2. For the new job I upgraded to the latest version (2024-11-04) and proceeded to rip the 80 discs.
In the process there were several occasions where a completely different CD recording would appear under one of the metadata sources, usually GD3.
For example, catalog MC "JAZZ CD 067 - Buddy Berigan - You've Got Everything", shows up correctly on AccrateRip Meta, Musicbrainz, Discogs, and Freedb whilst GD3 gives the recording as "Glenn Miller - American Patrol". Looking up American Patrol on Discogs I found a match for label "Past Perfect (2) – 204279-202". Why would that happen? What information is used to index all these CDs?
