Tracks belonging to album groups

[simbun]

Maybe I've been using it wrong, but I'd never really found a good definition of the tag; I've been using it to help define the logical structure of a CD/piece of music.
The CD in question was the second disc of a deluxe edition release that comprised the tracks from 4 previously released EP's, hence I had one CD with 4 groups with tracks in each.
Another example is where a Live album might contain tracks that were recorded across a number of different concerts. I know I could put the venue and date information into the title/subtitle, but having it grouped within the control point is also nice.

I don't have any classical music, nor do I have any experience of it, so I wasn't aware it was meant specifically (within MinimServer at least) to group the movements of a symphony. So I guess it makes no sense to say you have a favourite movement, or would want to play a movement in isolation...interesting.

Anyway, useful to know, I guess I'll keep using it in the way I do as I find the extra logical grouping to be useful at times, I just need to be aware of the inherent implications of it.
