It will depend on the person, but I think generally speaking, a song is but one aspect of an artist / the art of music; if you're a mass consumer that just has something playing in the background, it probably doesn't make a jot of difference (consider also "muzak" / elevator music), but if you're more of an active listener you may look into and enjoy the story behind the music and the artist as well.
Personally I think knowing the story behind music makes it better. The music isn't to everyone's taste, but for example Devin Townsend's wiki page / story is a trip: https://en.wikipedia.org/wiki/Devin_Townsend
Completely agree, but it seems to me there's a difference between "I like this, so I'm going to find out everything I can about who made it and why because I will enjoy it even more that way" and "I can't possibly like this unless I know who made it and why".
I think we kind of already have the answer to this one. Commercial music that use computers to enhance the song or singer is already prevalent. Even straight AI assisted track generation probably already happens. People don't use to mind it for as long as they don't know. Once they do, many still don't care but some feel betrayed and think honesty and humanity is part of the art. I haven't heard of a single person who refuse to enjoy songs they don't know how they were produced, though, and I strongly doubt the parent would too.
Would you refuse to enjoy food if it didn't come from a reputable source? Of course you would. You don't just eat shit at random.
If a friend recited a poem, would it matter to do if they read it off the Internet or composed it themselves? Of course it would.
If someone tells you they love you, does it matter if they are a robot or an honest human or a con-artist human catfishing you? YES, THAT MATTERS TO YOU. Yes you "refuse to enjoy" things that have suspicious sources.
I don't think those examples are equivalent at all. Food isn't just about taste, but could literally kill you. Not many people have friends who recite poetry. And as for love, that's something that takes years to meaningfully develop.
But, I barely know any musical artist's name today. Most music is just something to listen to at the gym. It's pleasant enough, but I don't dig in to know who is singing at all. Every source is equivalent to me, as long as it's pleasant to the ear.
Perhaps you're different. The only question is, which attitude is more prevalent?
That's a poignant question, but with an easy answer: If I didn't know, I'd probably enjoy it up to its imperfections. But I'd feel defrauded once I discovered.
Like so many people felt defrauded when they discovered that the Milli Vanilli leads didn't actually sing, and that wasn't even AI. https://en.wikipedia.org/wiki/Milli_Vanilli
Edit: I might add that I already suspect any illustration that even superficially looks it might have been generated by AI. This has ruined the enjoyment of so many people's artwork whose style has been co-opted by AI.
This is the thing. Live performance is always gonna be different than something from pre-recorded or AI generated. That's why music lovers like to go to live concerts and performances.
That's the thing about art: when people make general statements like this one, others will go on to create things purely to see what's outside the box.
