Music play-farming has been a thing for probably almost a decade by now.
Spotify divides the huge amount of money they get from subscribers each month, evenly among all the plays during that month.
Someone figured out ages ago, that since spotify has a free tier, that means that if you can get some tracks on spotify as an artist, you can then create an army of free-tier bot accounts and massively inflate the share of the money you get paid as an “artist”.
Of course, this comes at the cost of everyone elses legit plays becoming worth less. Its an absolutely disgusting scam and Spotify has been ignoring it happening for years.
Adding AI generation into the mix is barely an innovation.
Edit: And if you’re wondering how it works with services that don’t have a free tier, it is done by hijacking peoples real accounts, then having them stream the relevant tracks over and over. Either by stealing entire accounts, or infecting devices that are already logged in with malware that will open the relevant app/website and play the tracks over and over.
