[mb-style] [Clean up CSG] Box sets, aka, what defines a unique release?

[Brian Schweitzer]

Just a clarification: When I talked about a "single CD", I'm talking
about a non-box set release.  A release of, say, Don Giovani that
spans 2 or 3 CDs I would, under this suggestion, still consider a
"single" release as opposed to a Box Set release.  (Box Set style
combines the two as a single concept).
