Post something fun.

What type of music is suitable for listening to when using codex immersively?

This is a playlist specially customized for vibe coders.

This is the advice Codex gave me: Listen to music that has “low semantics, weak interruptions, and does not grab attention for a long time.” The core principle is not whether it sounds good or not, but don’t take away your language system and working memory.

The most stable categories: - ambient / drone / space ambient is suitable for writing code, reading documents, and advancing for a long time.

It has a low sense of presence and is least likely to draw attention away.

  • minimal techno / dub techno / deep house are suitable for high-intensity continuous operation, and the rhythm can support the state, but don't choose one with a lot of vocals.
  • lo-fi / jazzhop is suitable for low- to medium-intensity work and is easy to enter the "smooth mode", but sometimes it will appear too soft after listening for a long time.
  • classical / neo-classical / piano is suitable for writing, structuring, and reviewing, especially for highly repetitive instruments such as Baroque and minimalist piano.
  • Game / film soundtrack is suitable for immersion promotion, but the premise is not to choose one with too high a melody recognition and too high emotional fluctuations.
  • brown noise / rain / cafe ambience If you are easily distracted by music, this type of ambient sound is often more effective than music.

Not very recommended: - Chinese pop, rap, podcasts - strong lyrics, strong vocals, strong emotional ups and downs - songs you "like too much" because you will start listening to them instead of continuing to write.

If divided according to Codex usage scenarios, I would match it like this: - Reading code/thinking about architecture: ambient, drone, brown noise - Continuously changing code/working in batches: minimal techno, dub techno - Writing articles/writing prompts/organizing documents: neo-classical, ambient piano - Long solo sessions late at night: space ambient, game soundtrack - Poor status, easily distracted: pure ambient sound, no music.

The most practical experience: having lyrics = basically reduces efficiency; having familiar melody = easily distracted; Stable repetition = best for long codex.

I divide it into coding during the day/writing at night/high-intensity sprints/low-noise focus.

Coding during the day is suitable for getting into work, continuing to write code, and not wanting to be too depressed.

  • Tycho - Boards of Canada - Kiasmos - Bonobo's instrumental section - Hiroshi Yoshimura - Keywords: ambient, downtempo, minimal electronic Night writing is suitable for writing articles, writing prompts, organizing ideas, and reviewing.
  • Nils Frahm - Ólafur Arnalds - Max Richter - A Winged Victory for the Sullen - Joep Beving - Keywords: neo-classical, ambient piano, modern classical High-intensity sprint Suitable for continuous code changes, batch processing, and entering "don't stop" mode.
  • Deepchord - Basic Channel - Rod Modell - Monolake - Biosphere - Keywords: dub techno, minimal techno, deep minimal Low noise focus is suitable for you who are tired or easily interrupted by melody and lyrics.
  • brown noise - pink noise - rain ambience - cafe ambience without voices - space hum / air conditioner hum - Keywords: brown noise for focus, rain for coding, deep space ambient game/movie soundtrack flow If you want "immersion" but don't want to be too noisy, this type is also very useful.
  • C418 - Disasterpeace - Hyper Light Drifter soundtrack - Deus Ex soundtrack - Trent Reznor & Atticus Ross - Hans Zimmer's low-dynamic tracks.

Don't choose these, which will easily lead to the Codex working rhythm: - Chinese songs with lyrics - Songs that are familiar enough to sing along - Rock/metal with particularly strong emotions - Movie soundtracks with great rhythm changes - Jazz improvisational jokes that are too strong.

The most stable way to use it is to fix it directly to 4 Set: - 10 minutes after start of operation: brown noise - 1-2 hours after entering state: ambient / dub techn o - Write a document or prompt: neo-classical - During the fatigue period: pure ambient sound, don't play music.

A word of advice: use dub techno/ambient during the day, neo-classical/space ambient at night, and use brown noise when the state is poor.
