Title and placement follow the cited edition evidence. The linked album essay supplies cultural context; this position does not independently infer writing credits, duration or a recording match with a streaming file. The ten-track SRCL-2080 CD sequence is retained separately from the 1977 original date. Physical-edition sources use シティ; digital metadata uses シティー. Title variants in ぃ/い and ゅ/ゆ are preserved as aliases rather than treated as different albums.
