Heavy SerenadeMelody Box

NMIXX – Heavy Serenade (Melody Box) is one physical edition of the 5th mini album by NMIXX, released on May 11, 2026. This is a physical CD: disc, photobook and cards in one box.

The album holds 6 tracks.

The box declared by the distributor holds one photocard, one lyric booklet, one QR or NFC card, and 2 boxes. 6 photocards are announced. It also holds ID Photo Set and Digital, as declared by the distributor.

No POB is listed for this version in pocabase. A POB (preorder benefit) is a bonus from the retailer, never from the label: it changes from one shop to the next and is gone once the preorder window closes.

Heavy Serenade comes in 12 versions, among them Melody Box, Platform Album_POCAALBUM, Standard, and Heavy. The tracklist does not change from one version to the next: only the box, the photocards and the artwork do. Melody Box declares more items on these points: 2 boxes.

This is an official edition: bought from an authorised retailer, it counts towards the Hanteo and Circle charts, which measure physical sales in South Korea. EAN 8809954225925 points to this exact edition: it is the code to check before buying, because every version carries its own.
