This is often part of the puzzle. They only put the main part of the company name on the back of the CD, and leave off the actual country. EMI are so huge that they end up with a large complex spiders web of connections that would need a database of its own to sort out.
Lately I have seen more and more write-ups added at Discogs about how to spot the differences. Especially in areas like CD Manufacturing. I am all for using our own Annotation fields to put in much better descriptions on how it all works.
Even when I only know a little bit, I’ll add those notes. The idea being someone else will add more details, and between us we decode the mysteries of Big Business.
These examples we have a BMG logo for the imprint, a BMG Rights Management for copyrights, and maybe a DADC Sony for the manufacturer.
I still find the term “imprint” a bit odd to get latched into my head.
