> the algorithms no longer have the "delightful serendipity" they used to
There is a limit to "delightful serendipity". At some point, you will have heard everything you could potentially be interested in but not normally listen to. After that, it will be either not your thing or more of the same.
Also, algorithms don't read your mind, they just match your usage patterns (mostly what you are already listening to) to other people usage patterns and give you what they have and you don't. For example you may listen to psy trance, and the algorithm notices that many people who listen to psy trance also listen to folk metal, so it will give you some of that. And there is a good chance for you to like that even though it is a completely different genre you may not be aware of.
But once all the matches are done, that's the end. There may be a few paths left for you to explore, because you are an individual and not an average, and tastes change, but there is no easy way for any algorithm to find that. The only solution is to go with stuff you probably won't like, so, not so delightful serendipity. Or just give you more of the same.
