Sometimes you can't even tell. I was in an uber drive where the driver had this incredible playlist of Brazilian bossa nova. It was sublime and some of the best tracks I ever heard. He even said he loves the singer but cannot find their name anywhere. It turns out it's a youtube playlist that is fully AI generated and genuinely some of the best bossa nova you can imagine. I still hear that playlist daily tbh. Moreover, imagine if you are an independent musician, have a good voice, know how to play instruments...you could ask AI to generate hit tracks for you and then you can play them at concerts or shows and claim them for yourself
