Hello again!
Sorry to bring back up one of my old threads, but I recently tried running these tracks through the fingerprinter again (now with the strength set to "5" instead of "2", and a few new databases added) and still no results.
Although it is not set in stone, I will now have to presume these tracks were indeed composed specifically for these commericals, which is a more common reality of background music tracks in advertising than many of us library music fans might think.
Or who knows, these might somehow have come from an ultra-obscure library from this era that none of us have even discovered.
Thanks for viewing!
