Regarding Ed Smith - MusicBrainz , both of the “Smooth Jazz Christmas” release groups. I have both releases in my possession and have been updating the information for these, however I had a couple of questions.
The main question is if I should I merge these releases together? As far as I can tell, most of the songs are shared between the two. The 2011 release does have 8 extra songs, but also the 2007 release has a few that are not present on the 2011 release. Also, the songs are in a completely different order between the two. I looked at the wiki for what a “Release Group” was, but it didn’t really tell me whether this was two releases in a release group, or two separate release groups with the same name. I added disambiguations to both in the mean time with just their year.
The other questions is if I should make these release groups (merged or otherwise) an “Album + Compilation” instead of “Album”? Since these releases are 4 years apart and have shared songs, I assume it’s a compilation. But I wanted to ask to be sure.
