fa/gg/ here. What makes you despondent about AI? I've experimented with suno a lot and so far:
its melodies suck
LLM lyrics suck
can come up with cool simple riffs in a formulaic style like surf punk but it's utterly clueless otherwise
after throwing enough shit at the wall something that's genuinely interesting might stick. you could achieve the same result by a similar "throw shit at the wall"/automatic writing/do gas station meth and let your brain juices spill out of your noggin.
it's really good at creating soundscapes/prod but that might be my bias since I'm clueless about sound engineering and can barely dial in my amps
So the answer is to stop sucking.
