I listen to music from 3 to 10 hours per day, albums, songs,...

I try to remember band names when listening music when I'm outside, I have +1600 songs on my iphone and I (still) know +75% of the band names when a song starts.

the vast majority couldn't answer song name, album name... or even artist(!) without checking the display. That's algorithm-driven exploration right there.

A local college radio made a funny experiment where they'd approach young people w/ h.phones in the street and ask them what they were listening to

I'm only now getting around to doling out some 9's for... 2019.

Today I often listen to a couple of albums a day and can eventually not remember one. I rarely take the time to dive in deep and give myself room to learn to love something new. That would show in ratings, too, naturally.

Yeah I'm always very surprised when I see yearly tops with several hundred entries .. I personally don't rate an album or add it to my yearly top before at least 2-3 listens..
