Spotify

In that same article you linked it later says King Willonius, the comedian who produced it, literally wrote the lyrics himself . He literally said (and quoted in the article) 'I think it’s a misconception that people think AI wrote ‘BBL Drizzy'. Then it goes on to talk about how AI may be used for sampling, rather than to create new songs, but spends a couple of paragraphs talking about how it's complicated because of copyright law. And in the end, the song, BBL Drizzy, got pulled from Spotify because AI was used in its production. That directly contradicts OP first comment. I do agree with you that AI is better than I first thought at music, but it's far from perfect. But in any case, thinking that Spotify right now is secretly implanting AI songs is still bonkers (and without proof besides some random YouTube video).
