I reckon part of why it works well in this case is, because they are relatively popular (tens of thousands to millions of views) songs in somewhat niche genre. So maybe more similarity between users? In more mainstream genres, say Hip Hop, Rock, Metal, EDM i feel it is much harder to break out of the loop of sameishness although the genres have much more to offer.

Also in either case, I'm pretty sure, the vast majority of songs out there have sub 10k views and basically never get recommended. Just top of mind a few songs, that based on the list above you might like, but I think I would never have discovered via algorithms, unless I already happend to start quite close.

Roel Funcken - Balaklavskiy prospex https://www.youtube.com/watch?v=Z7WVGwb-9x8

Subheim - Foray https://www.youtube.com/watch?v=MQ7IHYSrquc

Klez.E - Nachtfahrt https://www.youtube.com/watch?v=hi-8wkccjsw

Altın Gün - Cemalim https://www.youtube.com/watch?v=j_J3-yr9GNI

Ok, the last one is fairly large, but it came to mind :) I do discover quite a bit of new music on YouTube, but only when I deliberately select a starting song and go from there, on the main page there is rarely something interesting. If there is music at all. I'm sure it would get a lot better if I'd listen music primarily via YouTube.
