I used it today for 8 hours and damm, I must say that it is quite good. Definitely better than the "keep playing song when playlist ends" or the curated weekly lists. I had to skip songs only few times and I didn't mark ANY as "dislike", where I often that to do so few times in a row on the other options.

Perhaps a change in how I use Apple Music made this better, cause I learned from some comment here or on Reddit, that the algorithm acts better if songs are marked as love/dislike to tell it the taste, not like in Spotify where it just goes along the lists or what I listened to in the past.
