It's a nice thought, but it depends on people disclosing that they used AI.
They've created a monetary incentive for people to hide their use of AI. Sure, they may catch the people who use commercial services which watermark their output but music generation can be done on relatively inexpensive (compared to frontier LLMs) hardware and there is no way to automatically detect it.
It's a good thing that Tidal is doing, I'm just skeptical that it'll do much except to make people more creative about hiding it.
