No one is really doing enough to combat AI music. I don't think that AI music has no place. However, I think it should be free and it shouldn't profit off the music it's copied/remixed from. I do not believe writing a prompt constitutes creating music. And I don't want it mixed in with real music.
I also don't like a lot of electronic music, before anyone asks, but that's not the same thing. Programming beats takes more skill than writing a prompt. I can see the slippery slope comments, but I don't think they hold much water.
Apple Music (one of the 3 things I use) says they are flagging AI music, but this won't be shown to consumers. Apple has lagged behind everyone else with AI, but apparently they are going all in this year. They registered genai.apple.com, but we don't know what they're going to do with it yet. They're replacing Siri with Gemini (Google), but apparently trying to keep it private. I don't really buy it.
