>there are often 3-4 great songs each week that get added to my regularly playlist.

I'm earnestly uncertain that a system with near total access to your listening history producing 3-4 great songs per week from the corpus of all human musical endeavour can be considered a "good" effort. Particularly when the 3-4 recommendations are jammed into a 60 minute playlist of otherwise questionable quality.

It’s better than my effort at finding music, and it makes Mondays a little nicer. My goal isn’t to find the best music ever, but to find new and interesting music more easily.

Have you compared against random sampling?

If it's randomly selected from the entire music library of Spotify, then it won't be good. Most of it would come from a long tail of bad or niche stuff.

For a practical example see https://en.wikipedia.org/wiki/Special:Random - odds of finding an article that's both interesting and high quality are low.
