The official credit reads 'w/ Bazzi', not 'feat.'. The artist is listed as HONGJOONG, not ATEEZ. There's no audio yet, only a pre-save link.

And this isn't a first overseas collaboration. In July 2025 HONGJOONG released 'Almost' with Bradley Simpson of the British band The Vamps, and in May 2026 'PITC' with Anderson .Paak and Jay Park. This is the third. Not a beginning — an accumulation.

Bazzi is a 1997-born American singer-songwriter. 'Mine' reached number 11 on the Billboard Hot 100 in 2017 and the 2018 album 'COSMIC' reached 14 on the Billboard 200, and Bazzi is still active — 'speechless' came out this July.

That's the last of the numbers. Now, the music.

The Stereo Opens at Once at 0.35 Seconds

I measured all 23 seconds.

The first 0.30 seconds sit near −48dB with the side channel effectively dead at −70 to −82dB. A width of −29dB is complete mono.

Then at 0.35 seconds the first sound arrives, reaching −27.4dB by 0.40. Twenty decibels in 0.05 seconds. At the same moment the mid share flips from 11% to 58% and the side leaps from −81dB to −28dB. The stereo opens all at once.

After that, through 3.90 seconds, it's a mid-range floor with the low end under 5%. At 3.75 seconds it sinks to −48dB.

3.95 Seconds, 27dB in 0.15

This is the teaser's first event.

The low-end share goes 4.3% → 34.1% → 53.6% → 68.5%, and the level −43.6dB → −30.4 → −22.9 → −16.6dB. Twenty-seven decibels in 0.15 seconds.

Right after, from 4.15 seconds, the side runs 3.8 to 7.7dB louder than the mid for a tenth of a second — the widest point in the first half.

Then from 4.30 to 7.40 seconds the low end falls back to 2–5%. In, then out.

It comes back at 7.45 seconds, wider this time. The low end reaches 51.9% and at 8.05 seconds the width peaks at +12.5dB — side at −12.8dB, mid at −25.3dB. The most spread point in the 23 seconds.

From 9.5 Seconds, It Empties for 1.5

And the second event.

From 9.50 to 11.00 seconds the level falls from −35dB to a floor of −51.3dB at 10.40 seconds. The low end is under 2%, and the side drops to −76dB, putting the width at −36.7dB by 9.90 seconds. Complete mono, effectively silence.

A 23-second teaser that leaves 1.5 seconds empty. That's 6.5% of it. The shorter the clip the more expensive emptiness gets — and it emptied anyway.

So: it opens the width in 0.05 seconds, puts 27dB in at 0.15, and empties 1.5 seconds at 9.5. It shows you the song's grammar without playing you the song.

Tomorrow at 1 p.m.

The writing, composition and arrangement credits haven't been published yet. We'll confirm after release.

If you're listening tonight, use earphones for these 23 seconds. Two points — 3.95 and 9.5 — and you can more or less picture the shape of what arrives tomorrow.
