I have had similar troubles.
kstuart has some thoughts, and there is some discussion about it in this topic:
http://yabb.jriver.com/interact/index.php?topic=78390I have been using the [Description] tag to specify which version of an album it is - though if it's the
original CD release, I have been leaving that field blank.
I now tag all my CDs with the Catalog number, and I have a custom search in the Links Bar that goes to
Discogs and usually takes you to the right page for that version of an album.
http:////www.discogs.com//search?if(!isempty([Catalog #]),&catno=Hexify([Catalog #])&artist=Hexify([Album Artist (auto)]),if(isequal([Genre],soundtrack,8),q=Hexify([Album] Soundtrack),if(isequal([Album Artist (auto)],Artists,7),,&artist=Hexify([Album Artist (auto)]))&title=Hexify(removecharacters([Album],/)/(“”‘’‒ʼ!,0))))
I find that this can be useful when I am trying to figure out what tags I want to apply, and to know when that version was released. It still needs a bit of work though, as it doesn't handle albums with multiple catalog numbers.
At this point, I'm tempted to add a custom tag to Media Center for [Release Date], leaving [Date] for the album's original release. I'm not sure.
I am running into the problem now where I have been seeking out better quality versions of some of my favorite albums since using Media Center, so sometimes I have two or even three copies of an album now. (CD, Re-issue/Re-master, Vinyl, or SACD) It's a bad path to end up on since physical media can be so cheap second-hand these days.
Or when ripping a SACD that contains both stereo and multichannel tracks. It's simple when it's a single album as you can just tag them as disc 1 and disc 2, but I just picked up a SACD boxset the other day where some of the discs are multichannel and some are only stereo, and I don't know what to do about that.
I think if you could use more advanced expressions for grouping, it could be sorted out by including the number of channels. The problem is that I want to group and sort by a number of things, but don't necessarily want to display all that information. (similar to how the [Album] group works)
