Doing music with the assistance of A.I. is fun and the results can be surprisingly good. At least if you just want some generic genre (or mix of genres) music. Just put in the lyrics and describe the generic isea what you want. If the results don't satisfy, just hit "generate more" to get another version until you are satisfied.
But actually making music - that's a different thing. If you want to have more control on the outcome there are advanced ways to control the generation. Also generating shorter clips helps to iterate and have more possibilities to steer the A.I. to the desired direction.
No matter how well you describe the outcome it's always more or less random. Results can wary greatly and getting exactly what you want might require quite many regenerations. Sometimes it feels that the machine just doesn't understand at all what you want and gives completely different outcomes no matter how many times you try. Other times you get almost the result you want, but there is just some small faults. Unfortunately there isn't a way (at least in the tool I use) to uae the generated result as a "seed" to more precise results and tey to fix those small faults. Often you just need to accept them and move on.
