I focus on Polygram releases that are released in Hong Kong, Singapore and Malaysia. Typically, the release packaging will list the distribution and marketing company as so:
Marketed and distributed by Polygram Records, Ltd. Hong Kong/Singapore/Malaysia.
This means that this release group (not necessarily this particular release) has releases marketed and distributed by Polygram Records Ltd. (Hong Kong subsidiary), Polygram Records Pte Ltd. (Singapore subsidiary) and PolyGram Records Sdn. Bhd. (Malaysia subsidiary). All these companies are listed on the packaging despite that the release is only released in one location. For example, I know for sure that the Malaysian subsidiary did not play a role in distributing the release sold in Singapore, but nonetheless it is listed on the Singapore edition.
Should I input all three companies for release-level relationships, even when not all three have actually played a role in marketing/distributing a release?
