Yep. It is mostly nostalgia as there isn't anything better than an AI curating a million songs based on our like/dislikes, but on a macro level, we are at the mercy of people who tune these algorithms.

Are we being 'nudged' to like certain genres or musicians because they are being promoted? Of course, this could happen with a DJ or traditional FM station too, but with centralized AI, you impart that 'nudging' on literally millions of people.
