I need some advice on untangling a mixed CD from an unmixed digital media release that seems to have been merged incorrectly at some point.
The two releases in question: unmixed + continuous mix DM and mixed CD. The edit history shows that the mixed CD was added first, then the unmixed DM release was added, presumably based on the mixed CD. This led to it sharing the recordings and having the wrong track times. At some point in history, they were unmerged, but later on were merged once more because the track times of the DM release hadn’t been corrected.
So it’s once again time to unmerge these recordings, but I’m not quite sure which release should get the new recordings. The CD release was added first, so you could argue that it should get to “keep” the recordings. On the other hand, the CD release has gotten new recordings in the past already, and those were then merged once again into the digital media, so should the digital media then get to keep those recordings? Finally, the AcoustIDs are important too. I have the CD release here, and I could attach the AcoustIDs to any newly created mixed recordings. I can’t do that for the digital media recordings, so those AcoustIDs would be lost. Moreover, looking at a sample of the recordings, they all have more than 2 AcoustIDs linked, and in each case, only one of the fingerprints has a length that matches the mixed CD.
So, assigning new recordings to the mixed CD would allow us to keep the AcoustIDs (provided I attach them again from my copy), whereas assigning new recordings to the digital media release would perhaps be more historically correct? I’m more inclined to go for the first option, since the history is already messed up anyway and the AcoustIDs could mostly be kept, but I’d like a second opinion.
