The tracklist of SIDE-B : MEMOIRS OF ECHO UNSEEN is not verified in pocabase yet. It stays the same from one physical edition to the next: the box changes, the music does not.

SIDE-B : MEMOIRS OF ECHO UNSEEN comes out in 2 physical editions: POCA and 1ST SINGLE ALBUM POCA ALBUM. From one version to the next the music does not change: the box contents do. What changes from one version to the next: the photocards, the stickers, the lyric booklet, and the QR card.

Across all versions, the box can hold 2 photocards, 2 sticker sheets, one lyric booklet, and one QR or NFC card. Every version announces 2 photocards. Part of the photocards are drawn at random: two copies of the same album do not give the same cards, which is what keeps trading alive between fans.

No POB is listed for SIDE-B : MEMOIRS OF ECHO UNSEEN in pocabase. A POB (preorder benefit) is a bonus given by the retailer during the preorder window, never by the label: it changes from one retailer to the next and is gone afterwards. It is often what decides where to preorder.

These are official editions: bought from an authorised retailer, they count towards the Hanteo and Circle charts, which measure physical sales in South Korea and feed the music show rankings and votes. No EAN is recorded for these versions yet. The EAN is the 13-digit barcode that names one precise edition: it is the safest check before buying.
