Maybe it depends on what you watch. I use Youtube for music (only things that I search for) and sometimes live streams of an owl nest or something like that.
If I stick to that, the recommendations are sort of OK. Usually stuff I watched before. Little to no clickbait or random topics.
I clicked on one reaction video to a song I listened to just to see what would happen. The recommendations turned into like 90% reaction videos, plus a bunch of topics I’ve never shown any interest in. U.S. politics, the death penalty in Japan, gaming, Brexit, some Christian hymns, and brand new videos on random topics.
Yeah. Those keys on the piano are E and F. You can see those notes in the sheet music for the title track. Those long rows of notes are a bunch of E’s and F’s.
If you hit the play button in the bottom left corner, you can hear a computer-generated version of the song. Real version here.
