I'll rephrase: I don't want to find the music. I want recommendation of music that I might like. I want a mostly passive experience, where I can click a like button to get more like that, added to feed. I don't want to actively search, because I'm doing other things when I listen to music. If I find a song that interests me, I'll listen to the songs "radio" to find similar artists. This is an acceptable use pattern.

> which in turn implies things like major labels, artists seeking or expecting breakout etc.

This is nonsensical [1]. I follow YouTubers have their music on Spotify. Some are just spoof songs.
