I just bought a lovely CD, Affairs of the Heart by Marjan Mozetich, Amazon ASIN B015JSMZHI . It is a 2015 reissue of a 2000 original. The 2000 original has Amazon ASIN B00005Y7MN and is in MB as MBID release/5335ef7b-8193-448b-8b7e-62d692923238.
Is the 2015 reissue CD a new Release within the same Release Group as the 2000 original? Or is the 2015 reissue a new Release Event within the same Release?
Part of what makes this difficult is that I don't see any description of what a Release Event is in Style/Release or Style/Release Group. If I ask the MusicBrainz "edit Release" UI to add a Release Event, it only lets me supply a release date and release country. Does this mean that for two physical CDs to be from different Release Events of the same Release, they must have the same cover art, label, catalogue number, bar code, etc.?
Part of what makes this difficult is that the two CDs are similar in interesting ways. They have the same DiscID, so Picard reads the new CD and instantly finds the old Release. Yet they are different in many other ways. For example:
- Cover art: different
- Label: different
- Catalogue number: different
- Release date: different
- Amazon ASIN: different
- Track list: identical
- DiscID: Identical
So, which is the 2015 CD? A new Release, or a Release Event of the same Release? Why?
