The “As heard on Radio Soulwax, Pt. #” (1-14) series doesn’t seem to be recognised by the Metadata scanner.
Pt. 2, by far the the most popular, is “tricky”, with the correct CD / track data only coming from the vinyl release on Discogs.
Did you rip the secret track before track one? None of my albums that have a “Track 0” have been recognised.
No, I haven’t ripped track 0, so I don’t think that’s the problem.
