I enjoyed the Weekly Discovery and Made For You playlists for years and its suggestion mechanisms were just what I needed. I could tolerate the terrible UI and other minor flaws of the app as long as the excitement of discovering new music continued. I also didn't like the special promotions, podcast recommendations, and other novelties, but the real value was there and it kept me paying for the service.
The changes started around 2020, when the playlists started to contain fewer songs and artists that I could call discoveries. I found myself in what could be called a music bubble, and it didn't feel like it was growing much.
Also, when I first started using Spotify, I spent a lot of time in the app and was more involved in the listening process. Now I was mostly just hitting the button, minimizing the window, and listening to music in the background. It became less interesting. I'd come back to the app occasionally to skip (or block) a track I didn't like. And then came the AI-generated tracks, which was the last straw for me.
Not that I hate Spotify, it's just sad to see it go the way of enshitification. It probably still meets the needs of millions of other users, but I'm no longer one of them. In fact, I'm grateful for the opportunity to be more conscious about my hobby again. I still have my mp3 library that I've been building since the late 1990s, and I still buy and donate to artists from time to time, so I just have to relearn how to do the things that AI algorithms have tried (and failed) to do for me.
