I don't think this is saying anything about more active music consumption where people are actually listening to it. I personally get annoyed if more than 20% of a mix is songs I haven't already upvoted so there isn't a lot of room to bring in weird knockoff artists into my streaming--in fact I saw a recent article that talked about the current problem with streaming is that 90% of profits come from titles older than 18 months so it is harder to break through with new songs (the opposite of radio-driven sales where most profits came from new albums). That seems to be the opposite of "no one cares what they listen to so spotify can just redirect profits wherever they like."
