It Keeps 18.9 Seconds Muffled, Like a Voice Through a Receiver

In three lines

• &TEAM's 'Mark on Me' took first place on KBS 'Music Bank' yesterday.
• It's the Korean second mini album, released on 8 September, with six tracks.
• The title track keeps its first 18.9 seconds under a low-pass filter and opens it at 0:22.5.

The Sales Figures Need Their Layers Separated

Several reports have run the numbers with different baselines mixed together. Sorted out, it looks like this.

Basis	'Mark on Me'	'Back to Life'
Release day	1,224,524	1,139,988
Hanteo weekly	1,357,357 (Sep 7~13, six days)	—
First week (7 days)	—	1,222,022

The 1,357,357 figure is a weekly count, and since the album came out on 8 September it actually covers six days. That's a different layer from what people usually mean by first-week sales. To compare like with like, put 1,224,524 against 1,139,988.

The physical album came out in twelve versions including nine solo editions. That's a condition worth reading alongside the sales figures.

Six Songs

Song	Length	Credits
Mark on Me	2:51	Gripp Clouston, Benson Funn
Good Boy	2:33	Bang Si-hyuk, Johnny Goldstein, Supreme Boi, HISNOISE, Curtis
Love Jang	2:41	Soma Genda
Accelerate	2:18	Chiz Stevens
Empty	2:56	Dwillie
Night to howl!	3:12	Soma Genda

'Love Jang' draws on the 1990s habit of writing your feelings in a notebook and handing it over. The Japanese edition arrives separately on 21 September.

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

At 0:22.5 the Filter Opens

I measured the title track in 0.25-second windows.

From 0:00 to 0:03.4 there is complete digital silence (−240dB). The first sound arrives at 0:03.5 at −25.1dB.

Then comes the device of this song: 18.9 seconds, from 0:03.5 to 0:22.4. It averages −26.8dB, but 99% of that energy sits below 1,051Hz and 6000~11000Hz is 0.01%. The whole intro is low-passed like a voice heard through a receiver.

Then at 0:22.5 the filter opens. In 50-millisecond steps: −13.9dB at 0:22.45, −8.5dB at 0:22.50, −5.0dB at 0:22.70. 8.9dB in a quarter of a second — and in that same quarter second the 20~150Hz share goes from 0.0% to 64.5% while the 99% rolloff widens from 1.05kHz to 8.6kHz.

The drop isn't the sound getting louder. It's the bandwidth opening.

It Cuts Twice More

At 0:56.5 a single 0.25-second window is severed entirely at −46.0dB. Then at 0:57.0 a lone sub-bass hit arrives with 20~150Hz taking 99.1% of the energy.

At 1:55.0 it stops dead again at −34.5dB, returning at 1:55.5 at −10.2dB with the low end at 96.8%.

Between them, the body from 0:57 to 1:55 averages −6.8dB with 20~150Hz taking 75.3% — a sub-heavy mix. Across 0:58~2:36, 86.5% of windows stay inside a 6dB band between −10 and −4dB, and the sample peak reads +3.23dB, over full scale.

So the body barely moves. All the dynamics are made by opening the bandwidth and by stopping.

There's a 17-Second Tail at the End

The fade starts at 2:44 and falls to −86.6dB by 2:53 — the point that lines up with the 2:51 track length.

But the video runs 3:08. From 2:53.5 to 3:08 there is a video-only tail of sub rumble, with 20~150Hz at 85.9%. That's where the 17-second difference comes from.

Just the First 25 Seconds, on Earphones

The design of this song is all in the first 25 seconds: kept shut for 18.9 seconds, opened at 0:22.5. On laptop speakers you can barely tell the shut state from the open one, because the point is 6000~11000Hz moving off 0.01% — and those speakers can't produce that band.

Try just the first 25 seconds on earphones. After that, the same trick runs twice more.

&TEAM are nine members — K, FUMA, NICHOLAS, EJ, YUMA, JO, HARUA, TAKI and MAKI — who debuted in Japan on 7 December 2022 under HYBE LABELS.
