I don't make music, but I know a couple producers/beat makers, and they all tell me it's basically the same argument people had about synthesizers back in the day. There was a lot of concern that synthesizers would make things too easy, replace musicians, or somehow make the resulting music less legitimate because a machine was doing something that traditionally required a person to play.
But that's what technology does. It takes things that used to require more time, specialized knowledge, or physical skill and makes them more accessible. That doesn't mean the creativity disappears. It means the tools change.
The most interesting things ive heard goes along the lines of
"Why spend x amount of time trying to match a sound someone wants manually when AI can achieve the same result with the push of a button? A human has to do all the button pushing and listening. Its not like me and the artist are just creating something, not listening and sending it out, I know I dont and i hope no one else is."
...
"It's like choosing to walk somewhere simply because walking came first, when we now have bikes, cars, and skateboards. The existence of something being done faster doesn't invalidate the old one. It just gives you another way to get where you're going."
..
"I probably save 2 or 3 hours a day now cause of how fast I can respond with an effect for a particular sound a client wants."
And I think that's ultimately what's happening with AI generated music. Whether people like it or not, it's becoming another tool in the creative toolbox. Once enough people realize they can use it to get a result they couldn't otherwise achieve, or simply get there faster, it's very difficult to convince them to stop using it just because the older method required more work.
Personally, I just like music. I have my real artist, but when it comes to the A.I stuff, If I need a vibe going for 2 or 3 hours of consistent sounding music, i'd rather just use A.I gen stuff because of how consistent it sounds from track to track. Its good with keeping the atmosphere going, but, the stuff that comes from my favorite bands, like Kool and the Gang, and Earth, Wind & Fire, they still have a special place in my listening.
