Opus 5.5 sparks "code as media" wave: songs and MVs generated purely by code

Developers are exploring a "code as media" paradigm with Claude (Opus 5.5): complete songs and music videos where every sound and frame is generated in real time by model-written code, with no samples, audio libraries, TTS, or off-the-shelf music APIs.

Confirmed

Developer ajdevsmith showcased a pop-punk single with MV (circulating around 09-23) and a rap "debut single" "No Samples", whose lyrics explain the implementation; all audio and visuals come from custom JavaScript written by Claude. The work was reshared by JasonDClinton, Syntetisaattori, YouJiacheng and others.
Reddit user buzzlaker, inspired by an earlier rap video, used Claude Code (Opus 5.5) to build a rap MV themed on "Dangerously Skip Permissions": beats generated with Python and other code, with vocals, beats and animation all code-generated, no samples or stock assets.
Reddit user v3rbxtim shared a similar pure-TypeScript rap project where all sound, including rap vocals, was synthesized from scratch.
Audio tech duo dadabots reshared the work, suggesting AI music has entered a new stage.

Why it matters

These demos show AI writing its own synthesizers instead of calling music-generation APIs, extending the model's capabilities in audio programming and multimodal creativity.
Multiple independent authors attempting similar projects in the same window indicates an emerging creative path rapidly being explored by the community.
