NMIXX has released the original highlight medley for its fifth mini album, “Heavy Serenade,” adding a second track preview after an earlier a cappella version. The JYP Entertainment NMIXX official website listed “NMIXX(엔믹스) ‘Heavy Serenade’ Original Highlight Medley” as a May 7, 2026 update, while reports said the video presents excerpts from all six songs on the album.12
The release places the highlight medley at the center of the group’s final pre-release schedule before “NMIXX Heavy Serenade” arrives on May 11, 2026 at 6 p.m. The album and the title track of the same name are scheduled to be released at that time, following a promotional rollout that included a pre-release music video for “Crescendo” and advance performance content.23

The original highlight medley includes portions of “Crescendo,” “Heavy Serenade,” “IDESERVEIT,” “Different Girl,” “Superior,” and “LOUD,” according to StarNews coverage of the May 7 video release.2 The selection confirms the same six-track structure reported in earlier coverage of the mini album.
Before the original highlight medley, JYP Entertainment released an a cappella highlight medley through official social channels on May 3, 2026. iMBC Entertainment reported that Lily, Haewon, Sullyoon, Bae, Jiwoo, and Kyujin presented parts of the title track and other album tracks without instrumental backing.4 The a cappella preview covered “Heavy Serenade,” “Crescendo,” “Different Girl,” “IDESERVEIT,” “LOUD,” and “Superior,” giving listeners an early vocal-centered version of the album’s material.4
The two medley formats serve different roles in the album rollout. The May 3 a cappella medley emphasized the members’ voices without instruments, while the May 7 original highlight medley presented excerpts closer to the official album sound. The available source material does not provide full song lengths or complete production credits for each track, but it does identify the six songs previewed across both medley releases.
