`queueSixAndOpen` filters the queue down to tracks that have an album, because `explore-link` renders a name it cannot route as plain text and one test clicks that name. The filter is right and unchanged; the comment explaining it named the wrong two files. Since #104 read a WAV's `id3 ` chunk, the two tracks under `Field Recordings/Test Tones` are tagged, scanned and ordinary. Asked of a seeded app rather than of the comment, exactly two tracks in the fixture library have no album: `unsorted/no-tags-at-all.mp3` and `unsorted/title-only.mp3`. The clause saying which change made the old names wrong is there so the next reader does not restore them. Closes #217
