Opus 5.5 writes a rap song and music video entirely in TypeScript
From one prompt in about two hours, Opus 5.5 synthesized vocals and instruments in code, mixed the track, and drew the rap music video frame by frame.
Someone on Reddit asked Claude Opus 5.5 to make a rap song and music video about itself, and it built the whole thing from scratch in code. 🤯 Every sound, including the rapping voice, was written in TypeScript. It took one prompt and about two hours. Here's what Claude did: → Researched memes about itself, then wrote the lyrics. → Built a voice synthesizer from scratch, with hand-written pronunciations for every word in the song. → Wrote a rhythm engine that puts every syllable on the beat. → Created every instrument from raw sound waves: kick, snares, hats, bass, piano, and an 8-bit lead. → Mixed and mastered the track. → Checked its own work with speech recognition to make sure the lyrics were understandable, then fixed what wasn't. → Drew the music video frame by frame
