SunoAI is very good in my opinion.
audio quality is still WIP and UI is ugly but prompting should allow more detail.
e.g., 70s Dolly Parton-style song rando made earlier today: https://sonauto.ai/songs/t4XGcHqsYwS6B73MjtV5
It seems designed for making pop music no one will listen to.
I have spent many hours with MusicLM making wild experimental music no one will listen to.
MusicLM has no problem making really weird sound combinations.
I just gave SunoAI some of my MusicLM prompts I have saved and the results are garbage. The problem with the AI test kitchen model though is the results sound like they are in mono.
The ultimate for me will be when we can make rap/hiphop no one will listen to.
