I think you're fundamentally missing the point being made here.
Yes, "-like" is commonly used as a suffix, in which case a hyphen is correct. But describing music as "audio-like" is clearly nonsense (music isn't "like" audio, it is audio), so that's not the sense in which it's being used here.
For clarity, the full sentence is:
> Genie 4 is natively multimodal, enabling audio-like music, ambient noises, and interactive dialogue to be simultaneously generated with the world.
