I suspect this is some trick somewhere with purchased views or something. Not that I'm against AI music. I love the various lo-fi / cyberpunk / etc. AI youtube channels. I also enjoy my own suno music. Overall, I'd say AI music dominates my listening these days.
It just seems unusual that a lot of people like the same thing. Even the channels on Youtube that I listen to are so prolific (people generate a large amount of music and just stick it in there) that I never go look for a particular track or anything. And there are so many of them that each one only gets a few thousand views.
