@joel @Geoff_Coupe I think you are on to something, but perhaps not as you describe. I do not think the two Albums are different versions, e.g., “CD” and “Vinyl”. Rather, they are the same version, with one being some kind of shadow of the other.
Here’s another example from the same crop of albums I imported from TIDAL. Here is how one appeared after the addition:
Note the Feb 1 2012 release date. Also note the absence of an ID for the composition “String Quartet in C major, D. 956”. Now let’s try to re-ID this album. At the start of the process, we see this:
At the top, we see the chosen album, and if we click on that, we will see the current set of IDed contents. Look here:
While all seems well ordered (correct times), look at Tracks 1-4. The ‘String Quartet’ is actually a String Quintet. But same opus, movement name, and time. And, if we were to re-select this match, the same result would take place (not shown). Namely, the quartet would remain and un-IDed quartet.
But if, instead, we scan farther down the list of possible album choices, a second “version” (loosely used) appears (too much vertical distance to display them both on one screen):
Note this one has a Date of 1993 on it, but appears otherwise to be the same. If we were to select it, here are its details:
Notice that these details are identical in all respects to the first “version” shown earlier (only the background changed slightly between photos). Even the date is the same (curiously, 23 AUG 2003).
BUT, there is one major difference. When we select the second “version”, the compositions are now IDed as shown below:
My inference: Faulty, phantom, or multiple database pointers are being created in the importing process from TIDAL to Roon. This could explain why all 33 albums failed to truly ID contents. It may also explain why users (myself included) have found duplicate identical Artists in their libraries.
I’m calling it a bug.
