"The only people actually paying to use this are folks gaming streaming platforms, and for background music in ads (which is a trend that really needs to die)."
That's a pretty big generalization. I've been writing songs and recording original music since the late '80s. I've had a lot of fun playing around with Suno feeding it old demos to play around with new arrangements or feeding it new recordings of just voice and guitar (or even just voice). I know other musicians doing the same. I haven't released anything generated by Suno (heck, after all these years, I've actually only ever released an E.P. of original (completely non-AI) music I recorded with my daughter), but I've got some hybrid works in progress, where I've downloaded stems of several different Suno renders, imported them into my DAW (Cubase), picked and chosen the elements I like the best, and recorded my own vocals over them.
On the Suno groups on Facebook, I've seen people claiming that lots of musi industry folks are using Suno for rapid demo-ing and then going back and replacing the instruments. There's a service called Musiversal which has a stable of human musicians who work remotely who have even been marketing themselves as a way to re-record AI tracks.
