I can't get Suno to obey the style tags, it's as if they are not used at all in generating the output, or massively changed. Maybe they do the same trick Gemini used to generate the black queen of England. Or it's a trick to waste our credits faster, the only way to get something decent is to spin the dice many times.
Still not totally adherent, but if you can steer it with genre, detailed descriptions of genre, and elements of the genre it's way better than v4. Some descriptions work better than others so there's some experimentation to figure out what works for what you're trying to achieve.
You can also provide descriptions in [brackets] in the lyrics that work reasonably well in my experience.
