## When to use ElevenLabs Music

ElevenLabs Music's strength is **structured songs with real vocals** — it takes a style brief plus lyrics with section markers and returns a coherent, mixed track. Pick it for:

- **Full vocal songs** — verse/chorus structure, multilingual lyrics, consistent meter
- **Instrumental beds** — `force_instrumental: true` for background music, podcast intros, game loops
- **Short brand assets** — jingles, stingers, theme music (5–30 s)
- **Long-form tracks** — up to 5 minutes in a single call
- **Commercial work** — output is commercial-friendly

If the user just wants ambient sound or a one-off SFX (thunder, footsteps), that's a sound-effects task, not music — ElevenLabs Music is for *songs and tracks*.
