There is something wrong with the algorithm, where even when it does force you to listen to artists it knows you likes, there is no second layer which says, "this person loves Fleetwood Mac, I can disregard their top 5 most popular songs and allow a selection from their too 50 songs now."

It's not that google knows I love Fleetwood Mac is the issue, it is that they don't know that. They think I just love 4 songs off Rumours.

Same with The Band. Google wants me to listen to the band once every 3 or so hours, but only the weight and the night they drove old Dixie down. If I search a specific song, it never gets added into rotation.

I haven't noticed this issue with newer artists. The algo gives them much less priority, but seems to be willing to play more of their catalog.
