I used to be able to just start a “smooth jazz” or “lo-fi” playlist and the algorithm would do its thing, but now I need to specifically look for “classics” or some such otherwise the slop shows up. I’ve not yet had this issue with the rest of my musical landscape though as that does default to real bands, but these “background” styles are definitely affected.

Didn’t even have to type it out you took care of it already.
