I don't grant it. if you mean it is impossible to tell from the music itself, perhaps. but there are other means of verification.
What are any reasonable examples of how you can verify a song wasn't AI-generated?
e.g. Game speedrunners film the whole process to prove they did it themselves.
Presumably you had some ideas when you envisioned "human-verified platforms".
A human can still upload tons of AI generated music though?
I don’t see how verifying that the author is a human helps in any way.
I also don’t think it’s a big problem but that’s another discussion
