It seems that solution could be in the form of utilizing the \\, which I recently picked up from here:
That would show nicely any number of additional album names- but only in the Extended tag fields. And unfortunately in the Tag Panel or in Columns it would look bad; while in Winamp I would see only the first name
And overall this would more of a technical solution, and not a one being among the lines of being a concept. And so, even if utilized, it will still bring back the same problem: how to sort [alphabetically] such albums? Which name to choose and how?
