I don't at all like that it's buried in the beta webapp. But it works, once you get thru Apple's aggressively defensive login system (which, sure, it protects all my stuff; be defensive).
So clearly it only tracks Apple Music playtime; I mostly use my local music library. Anything here is stuff I don't own, or on an Apple playlist. And the two extremes: '80s pop music, and '90s industrial/metal. I don't understand some of these, why are there 5 plays of Rammstein's DEUTSCHLAND but nothing else off that album? I much prefer Engel.
