Random style generator

Why a structured roll beats a random word soup

Pure randomness produces prompts nobody can learn from. This generator rolls inside six fixed slots — genre, mood and energy, vocal, instruments, production and tempo — so every result is a complete, balanced instruction rather than a pile of adjectives. Because the slots are stable, you can compare two rolls and say exactly which dimension changed.

Lock, roll, repeat

• Roll re-rolls every unlocked pillar and leaves locked ones alone.
• Roll all clears every lock and starts from a blank slate.
• Roll this on a card re-rolls that single pillar — useful when one slot is the only thing you don't like.
• Lock freezes a pillar you want to keep across the next rolls.
• Keep saves the current line to the history list below.

A productive loop: roll until the genre and mood feel interesting, lock those two, then roll the remaining four a handful of times and keep the two or three versions you'd actually generate.

Treat the result as a starting draft

A roll is deliberately generic — it has no idea what your song is about. Take the combination into the builder and replace at least one phrase with something specific to your track. The roll's job is to break a blank-page stall, not to write the final prompt.

Where history lives

Kept rolls are stored in this browser under the key us-random-history and capped at ten entries, newest first. Nothing is sent anywhere, and clearing your browser storage removes them. If a combination matters, copy it somewhere permanent.

Using rolls as a listening exercise

Generate from three consecutive rolls that share a locked genre and compare the results. Hearing the same lane through different vocal and production settings is a fast way to build the vocabulary that makes deliberate prompts possible later.
