The sad thing (for artists) is that it seems like most Spotify listeners don't care.
Most of our music consumption today seems to be as a kind of background vibe rather than an appreciation of the music itself.
I am the kind of listeners that care, but to be honest, indeed most people don't care, and what Spotify does is taking advantage of that fact which makes business sense.
Most people just listen to "chill music" and never care to find out the musicians behind the tracks. They may not even realize that lots of tracks sound very similar (for good reason -- they are created by the same musician[s]). They just need some music while studying/working.
I play instruments myself, and I force myself to listen to many different styles of music and delve deep into artists' works, so that I can be a better (amateur) musician. I don't listen to Spotify "chill" playlists, not just because of the practice described in this article, but because I could actually tell that the music was repetitive and low effort, and I can never find more albums made by those musicians when I occasionally find a track that I find interesting. Can you expect other listeners to think this way? No.
