Does that really matter? Eventually it will be 99%, but even then I am not necessarily concerned until it crowds out human created songs.

Before AI, 99% of anything was trash and now with AI, perhaps 99.9% is. But the thing that matters is whether the remaining 1% or 0.1% is good or meaningful for us or not. Though I guess soon enough even AI music will be meaningful for us, but I don't think this precludes the existence of human musicians.

People who have been listening to music their entire lives isn’t the target audience. It’s mostly getting the young generations used to it, and accept it as a norm. Something about most people’s music taste formalize around high school/university times.

It’s close to how young people have never experienced pre-Fortnite/Roblox times, so they are fine with shelling out money for microtransactions.
