I don’t use shorts and for a long time I didn’t use YouTube music either (despite paying for premium). I now use it because it’s rather good.
And YouTube’s recommendation algorithm is crazy good, but you have to tune it. It’s a tool. You tune it by not watching shitty videos you don’t like; if you do, remove them from your history afterwards and hit thumbs down on them. Subscribe to channels you like and thumbs up videos you really like. All these things are strong signals and the recommendation algorithm will vastly improve if you do this.
I mean it when I say it’s the absolute most useful tool there is in terms of discovery on the web.
But yes their search sucks more ass than a donkey vacuum.
