And, at least for me, the recommendation is by far better, than Spotify was. I had Spotify premium, liked a lot of songs, tried to use it regularly. And when it went on its on after my playlist finished, 5 out of 10 recommended songs were…shit. No matter how much I tried to like or disklike songs. When they started current YT Music (after the Play Music shutdown), I tried it and it was leagues better from the get-go (the recommendations, that is). I assume that’s because they have my 10+ years old YT history. Anyway, I cancelled Spotify and happily use YT Music.
I’m well aware that it could be different for everybody.
