CD matrices and when to add a new release

I have a copy of Pink Floyd’s The Division Bell that I have narrowed down to this release.

https://www.discogs.com/release/14332651-Pink-Floyd-The-Division-Bell

I checked the existing releases and believe mine should be added as a new one, but wanted to confirm as it does partially match https://musicbrainz.org/release/65ee4ee0-2eb7-33f9-b1b3-aeb8b192a66c?tport=8000. I have only a cursory understanding of matrices and didn’t want to add another unnecessarily.

Are the pressing plants the same too? Style / Release - MusicBrainz says matrix numbers are a grey area:

Whether different CD matrix info should always be separated is an open question; for now, do not merge them if another editor has made the effort to split them. Different pressing plants require different relationships and as such different releases.

The Discogs and MusicBrainz pages you link are different releases. The discog page links to https://musicbrainz.org/release/cba16f46-59a9-4cc8-9105-305d2d39dd95

So what are your matrix details? Why do you think it is different?

Hi jgreene5, you should generally add it as a new one. If you are only using it to “add to your collection”, you don’t need to do the extra work to import another one. If you want to update the release with details of your own, you should be careful to make sure you aren’t overwriting other valid details of another release.

I’ve added the Discogs release you’ve linked to MB: https://musicbrainz.org/release/cba16f46-59a9-4cc8-9105-305d2d39dd95

Your release (the release on Discogs) is currently not on MB. …or, at least, it’s not linked to a MB release.
This release comes from a different pressing plant than the one on MB - DADC Pitman vs. DADC Terre Haute. A different pressing plant requires a new release.

However, there is a problem here: The release shown on MB (images) does not correspond to the one linked on Discogs, but actually to your release. Look at the disc (rim text and the additional “DIDP 081417” above).

I would add a new release and remove any conflicting images from the other.

As a disambiguation, I would refer to the CD print (rim text) and not to the matrix.

My matrix had the DIDP-081417 that was showing in a couple of other releases, but ended in “K2 2A 19” rather than a 1 or a 2 (if my memory serves me correctly). I have uploaded a scan to the link that agatzk kindly provided.

Thank you for doing that agatzk, that made my life easier!

Thank you for the information, ernstlx. I was going to ask for disambiguation suggestions if I needed to add the release.

I wasted everyone’s time on this, my version is the “Hit Savers Platinum” version. I must have overlooked it when searching for my release. My apologies to everyone, but thank you for all the suggestions. They will be a big help going forward.
