Yes. I'm having fun making an indie game, which will most likely never see the light of day, let alone profit. I'd definitely pay cents to dollars to have fitting background music. There's no chance I'd pay for a human musician.
Why not? The experience of working with a freelancer for a piece of creative art is more or less like prompting except they take longer to reply, understand better most of the time, write/spell worse, but produce way better results, especially after two/three iterations ("prompts").
It really depends on what you want/need, augment/extrapolate your own creativity with AI tools, or invite someone else's.
The AI debate is for now most often centered on whether AI is capable of replacing individuals, but replacing the results you get when you put multiple humans together is another dimension entirely.
Then, if the project lives and grows long enough to be published, you start soliciting involvement from human artists but with minimal budgetary commitments. If your project gains momentum, you start allocating more realistic incentives for human collaborators.
I'm a very long way from that though.
