I believe it will depend on a couple different factors. Putting keywords into a generator isn’t the same as laying your hands on an instrument, being able to physically play it yourself. However, if the result is so perfect and beautiful that a person could have never possibly come up with it on their own, it might be discouraging (but I can’t really see that happening)
This assumes music is made and enjoyed in a void. It’s entirely reasonable to like music much more if it’s personal to the artist. If an AI writes a song about a very intense and human experience it will never carry the weight of the same song written by a human.
This isn’t like food, where snobs suddenly dislike something as soon as they find out it’s not expensive. Listening to music often has the listener feel a deep connection with the artist, and that connection is entirely void if an algorithm created the entire work in 2 seconds.
