// some *other* (much more commonly referenced) track by directory instead
// of more naturally by name.
//
// See the implementation for an important caveat about matching the original
// track against other tracks, which uses a custom implementation pulling (and
// duplicating) details from #find instead of using withOriginalRelease and the
// usual withResolvedReference / find.track() utilities.
