Two values of Albumtitle would be nice

[simoncn]

The internal design of MInimServer allows an item (track or group) to belong either to a single album or to no album. Allowing an item to belong to multiple albums would be a major change.

As DISCSUBTITLE is already supported by MinimServer, this is the recommended solution.

In the future, it is likely that ALBUMGROUP will also be supported (see this post), which would provide another way of doing this.
