These go as far back as August 2016. It’s a nice, official resource for catalog number and barcodes - including digital releases, in which case it is often quite hard to find such metadata.
Soulfood, a German distributor publishes weekly brochures of their stuff including cat#, EAN, price code, tracklists and more juicy info.
They also list newest releases on their website.
AFAIK they started doing that in 2016. I had some moderate luck scraping with wget. Old links are long gone. Not much in Wayback Machine either. Anyone interested?
Maybe this can be made a general thread. Otherwise please split my post into it’s own topic.
