In Albums view, the rule for MC is that it groups albums by album name. So if your 16 bit and 24 bit version of an album both have the exact same album name, they will be considered the same album. "unified" as you put it. I kind of like that word choice actually.
One solution is to change the album name of one of them to something like "Dark Side Of The Moon (24bit)" or "Dark Side Of The Moon (DVD-A)", or something else that makes sense for it.
Another way is to change your albums view to group your albums using both the [Album] field and another field like [Bit Depth]. That would automatically separate albums out based upon the properties of the files themselves. But then you would end up with:
Dark Side Of The Moon - 16
Dark Side Of The Moon - 24
...or something very similar depending upon how you define your view.
You could also make a custom field for this to contain identifying information for the album. I called mine [Album Info]. My Albums view groups albums based on [Album Artist (auto)], [Album], and [Album Info]. In the [Album Info] field, I put things like "SACD" or "DVD-A" or "Mobile Fidelity". So it can contain all kinds of information about different versions of the same album.
But... (you knew this was coming right?) ... It's not perfect. Because JRemote ignores all of this grouping stuff and does it's own! So if you use JRemote (or other remote views) this might not work for you.
Because of the JRemote problem, I gave up on the (somewhat) elegant solution above, and just rename Albums to include information that identifies the particular album (like adding DVD-A to the title). Simple is simple and it works well with all of MC's interfaces.
Our member here @ferday has a huge number of different versions of the same album. I can't remember what his final solution was. I'm not sure if he will read this or not. You might PM him or start a thread about this on the Windows forum where he will be more likely to see it. As will other knowledgable members.
I hope that helps.
Brian.
