Try "Sparse intro" to get rid of intro vocals

If you want to get rid of annoying vocal yelps/moans/oh yeahs in the intro, try covering, then start the prompt with "sparse intro" (e.g. "sparse intro, drum forward, 1980s classic rock / heavy metal"). Since it's a cover, you don't need a detailed prompt. For some reason, word order seems to matter a little.

This has worked for me a couple times. Then don't have a tagged [intro] section in the lyrics. Not deterministic, but the RNG may tilt more in your favor.

Let me know if you have found other solutions that work for this!
