Issue 7 — One Audio Channel Per Customer

2026-W30 · 2026-07-20

This Week’s Slacking Forecast

Favorable: the three-minute concert — one song, eyes closed, doing absolutely nothing else. Instrumental playlists for spreadsheet weather. Humming in the stairwell, where the acoustics flatter everyone. Unfavorable: lyrics underneath deep work. Reopening the office speaker debate — no recorded winner. Drumming on the desk during someone else’s call.

Welcome back. Issue seven covers the music you can work to, the music you only think you can, and a llama with a career in software.

The Science of Background Music

Attention does not multitask. It time-slices, and when two jobs demand the same circuitry, both get worse — psychologists call it the dual-task cost. The cruelest collision happens in language: lyrics run through the same verbal machinery you use to write and read. Decades of “irrelevant sound” experiments keep returning the same verdict — changing, speech-like audio erodes verbal short-term memory even at low volume, and even when you would swear you have tuned it out. The brain attends to words on its own schedule and bills you afterward.

None of which makes music the villain. For routine, repetitive work, familiar instrumental music reliably lifts mood and alertness — and familiar is the load-bearing word, because a new album demands attention the way a new colleague does. Save it for the commute. Hence the office rule of thumb: silence, or wordless sound, for work made of words; the playlist for filing expenses.

There is also the option of flipping the whole arrangement: promote the music from background to break. Play one track and do nothing else — issue one’s detachment principle, arranged for headphones. Or take the third path: a game where sound and action were never separate jobs to begin with. Rhythm games weld the task to the beat, so there is no second task left to interfere with the first — which brings us, conveniently, to this week’s pick.

This Week’s Pick: Tile Rhythm

Tile Rhythm is four lanes of falling tiles and one rule: tap the black ones, never the light ones. Your score is the unbroken run itself — one wrong tap, or one black tile reaching the bottom unclaimed, and the performance is over. Four habits:

  1. Tap early, and anywhere on the tile. A black tile is fair game the moment it appears, and the whole tile is a hit zone, top to bottom. Waiting for it to reach the bottom edge is a handicap you invented yourself.
  2. Read rows, not tiles. Each row of four holds exactly one black tile. Hit it and the row is settled — send your eyes up to the next one instead of riding the traffic down.
  3. Eyes high, fingers low. Fix your gaze near the top, where rows are born, and let peripheral vision confirm at the bottom. The crisis is never at your fingertip; it is two rows above it.
  4. The tempo is score-driven. Every note nudges the speed up a notch until it caps, so a long run is one slow crescendo. Keep a metronome in your head and refuse to sprint — the hurried finger picks the wrong lane, and the whole song goes with it.

This week’s challenge: string 30 notes into a single run on Normal. For the record, Daily mode deals everyone the same tile chart, so the bragging is auditable. And if you want to know what raw hardware you bring to the concert, Reaction Test will measure it: Best-of-5 averages five rounds, and a single jumpy too-early click voids the whole series — the most honest cure for rushing on this entire desktop.

Retro Corner: The Llama of 1997

In April 1997, a teenage programmer named Justin Frankel released an MP3 player called Winamp under the company name Nullsoft — the name itself a wink at Microsoft, null being even smaller than micro. The main window was the size of a Post-it note, and it caught an entire era: CDs ripped into files, files lined up into playlists, an equalizer with sliders that begged to be fiddled, and thousands of community-made skins that could dress the player in chrome, wood grain, or leopard print.

Bundled with it came a demo clip in which a voice solemnly announced that Winamp “really whips the llama’s ass” — a tribute to Chicago musician Wesley Willis, and the moment one llama became MP3-era royalty. AOL bought Nullsoft in 1999; Frankel remained magnificently ungovernable, at one point releasing the file-sharing program Gnutella from inside the company, which AOL took down within hours — roughly the corporate equivalent of grounding a teenager who holds the house keys.

The skins mattered more than they looked, too. They belonged to an era when software had furniture and a personality — the same impulse that gave this site its beveled buttons and its boot chime. Winamp let your music player be yours. The llama was just management.

See you next Monday. Be kind to llamas.
