To this point, I've been using Qobuz as an alternative and it's recommendation engine is laughably bad, but the experience is somehow better. I'll get the most random songs pop up in the list, and sometimes it's a very pleasant surprise.
In the world of music discovery a bad recommendation engine is maybe better than a hyper-fine-tuned one.
FWIW good old Pandora now has options to influence their how their stations explore (so, you can for example pick “discovery” to have it try and find similar artists it hasn’t shown you as often).
