Generate music using Suno via kie.ai. Supports V5.5 (custom style), V5 (best quality), V4.5+, V4.5, V4. Up to 8 minutes. Great for game music stems, ambient tracks, and jingles. Polls until done and downloads to kie/assets/raw/.

Simple mode: pass text (+ optional voice_name).

EXPERIMENTAL (#20) — STEP 1 of Suno custom-voice cloning (FREE). Submit a clean vocal sample; polls to wait_validating, after which kie sends a verification phrase to your KIE_CALLBACK_URL for the voice owner to read aloud (then use create_voice_clone). ⚠️ Only clone a voice you OWN or have explicit permission to use. The completion step is not verified end-to-end and needs a real callback URL.

EXPERIMENTAL (#20) — STEP 2 — after the voice owner records the verification phrase from prepare_voice_clone, submit that recording to finish the voice. On success returns a voiceId usable in generate_music. Unverified end-to-end.

EXPERIMENTAL (#20) — retry a failed/incomplete custom-voice task by its task_id.
