I have a CD copy of Perennial Favorites by the Squirrel Nut Zippers. It’s an enhanced CD - 12 audio tracks plus a data track. When I look up the disc with Picard, it gives me disc ID _jI4UgPrJf4dV8NUULbCSFbZZYU- which is linked to a 12 track release.
The 12-track release is linked to a discogs entry that’s marked “enhanced”. In fact discogs doesn’t list any non-enhanced version. My suspicion is these are really the same version but due to vagaries in disc ID generation they were separated.
Is there a way to make Picard include the data track when computing the disc ID? Or are there other tools to calculate a disc ID that include it?
