How is it possible for 44% of new music uploads to streaming platforms to be AI generated? How is it automated at scale?

I'm not trying to spam streaming platforms with endless content, I'm just curious about AI in media creation generally. I'm trying to understand how 44% of new music uploads being AI is possible, even with the ease of generation with platforms like Suno.

I understand how easy it is to go from prompt->song, but is there some other element that makes the volume possible? Are there pipelines where people are just running endless scripts into the Suno API, and then automating its distribution? Are people using other agents like claude to automate the process? Is it driven by individuals or are there groups/companies that are behind it?
