Multi-disc DiscSubtitle sorting

[simoncn]

DISCSUBTITLE is just a way to give a friendly title to a numbered disc of an multidisc album as a substitute for Disc 1, Disc 2, etc. It is a standard tag, not something invented by MinimServer.

I understand your suggestion but I don't think using DISCSUBTITLE as a way to group related albums together is consistent with its intended purpose. For this, something like an "album set" concept (as discussed in some previous threads) would be more suitable.
