I really wouldn't recommend AI music, because actual human-written library music (And actual human-written music in general) has tons more creativity, ideas and soul than low quality AI. Not only that, but AI also steals from other creators without consent and gets things wrong as well, plus, generating music with AI degrades cognition. If you want to make some music, you have to put effort and actual love, care and ideas into it. The song doesn't have to be an original idea, nor does it have to be perfect-sounding, but you still got to put effort and work into it, instead of using generative AI.
