Heavy SerenadeStandard

NMIXX – Heavy Serenade (Standard) 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 photobook, 4 photocards, one postcard, one sticker sheet, and 12 lyric booklets. The photobook runs to 68 pages. 4 photocards are announced. One photocard is drawn at random out of 6 designs: two copies do not give the same cards.

3 POB are listed for this version: KPOPHERO Wholesale gives Poster : First Press Only (Random 1 out of 2) and KpopB2B gives Poster : 420×297 (mm) / Random 1ea of 2ea *First Press Only. The preorder window at KpopB2B closes on April 28, 2026. 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 Standard, Platform Album_POCAALBUM, Melody Box, and Heavy. The tracklist does not change from one version to the next: only the box, the photocards and the artwork do. Standard declares more items on these points: one photobook, one postcard, and one sticker sheet.

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 8809954225918 points to this exact edition: it is the code to check before buying, because every version carries its own.
