Discsubtitle groupings

[simoncn]

I am with you in preferring to merge multiple discs. When I made this the default for multidisc albums, I didn't realise how many people prefer discs to be separated. Various tweaks since then have attempted to strike a difficult balance between different preferences for how to handle this, unfortunately making the rules more complex with each change.

Rather than adding yet further tweaks such as overloading DISCSUBTITLE, a better solution that meets a number of requirements would be a flexible way to map the physical structure of discs and tracks to a logical hierarchy that can be configured to suit the user's requirements. This could include a level above album for boxed sets and a level below album and above disc for subdivisions such as the acts of an opera. The latter should also satisfy this requirement of yours. This is not imminent but might happen after some more urgent work items have been completed.
