Some of these could be more "modern" library cues as in 1990 - present, which is why you would find no info on them on discogs. CD only issues never got out to the general public second hand as much as the vinyls did.

The other reason could be that some of the titles are from the vinyl era, but were changed/retitled if they're from archival CD compilations.

These tracks are definitely from the vinyl era (1960s-70s, maybe a few 80s as well), and definitely aren't from the modern library era. If you listen to them, they're obviously archival recordings (although "Happy Wake Up" and "Sunshiny" could've been "remixed" for that particular library album, but unlikely). These are likely tape-reel only tracks, only I don't know which albums they might be on. Anyone got a Berry catalog on them?

Sonoton did not have any "tape reel only" tracks. If any library had vinyl available, everything they issued in that era was all available on vinyl (and other formats) at one time.
