- Four-bar lines with clear rhymes rap more cleanly than long sentences.
- Put tempo and delivery in the style box: “fast flow”, “laid-back”, “confident”.
- Describe a sound, not an artist. Only use lyrics you wrote or have the rights to.

- Make a music video turns a song into a beat-synced AI music video in the same studio.
