I always include the word Horror in the genre, makes it dark sounding. I tell it to make 80's early 90's Industrial Cyberpunk. Usually adding a bunch of genres makes it sound more interesting. The A.I. is so good that almost every output sounds pretty good so I don't have to tweak it too much. It makes about a 2 minute song on Udio then I ask it to make an intro and usually extend the song with instrumental and then alternate with lyrics, after that make it give an instrumental outro . When adding a new section you have 4 variations and I listen to them and choose the best one, usually don't have to re-prompt. It does take some time. What I liked about Udio is you can make longer prompts that gives much more direction, I don't specify instruments, I just give it a direction on content for the lyrics. Too bad I can't use Udio anymore. Right now I am using Music GPT...you can make longer prompts but the songs sound more emo or poppy...so I always use the word Horror and sometimes Experimental in the genre to make it sound more raw
