REQUEST · 2017-11-22 · ordered position 13 of 16.
“Good bye（Previously Unreleased）” occupies position 13, listed track number 13 in the 16-track WPCL-12756 edition of Mariya Takeuchi’s “REQUEST”. This CD release is dated 2017-11-22; the album’s original year is 1987. The title and position together identify a particular place in this edition’s program.
In this sequence, it follows “夢の続き（'89 CD Single Mix）” (12) and precedes “恋の嵐（Karaoke）” (14). The source explicitly classifies this position as a bonus track, so its presence here should not be used to reconstruct the original album’s running order.
The related “REQUEST” essay supplies the album context. This entry adds the edition-specific title and placement without assigning writing or recording credits merely from a matching name. A shared title, release date or remaster label does not by itself establish audio identity across editions.
