To +1 the general "youtube music is youtube": every time I've given the YT music app a try, I've started listening to [what I wanted] only to end up in random youtube mixes (not YT-music-mixes of just studio-uploaded stuff, youtube videos titled "mix" or otherwise, sometimes 10h long, with accompanying looped graphics and sometimes VPN advertising segments and like-and-subscribes strewn throughout randomly) after a few songs.
YTM is YT plus music, not a separate thing. It's very clearly intentionally forced to be that way. It's the primary reason I think it's an awful service (the general UX is a very close second). It does, however, have the benefit of niche user uploads like this existing because it's YT.
I believe the links. The guy is searching for fringe stuff. You can even copy watch ids from YouTube, which is likely what was done here.
But if you are any ordinary user and you are searching on YouTube Music for a playlist and somehow you got a 10 hour random person's video, either you're spectacularly terrible at search, or you're full of shit.
Look, I can link to random stuff too. A couple of YouTube curated playlists, and some of millions of albums. All songs direct from publishers. Zero imaginary ads, or bizarre "videos".
Incorrect. All of those links are taken from the YouTube Music app on Android via search. Some are contrived, but the point is that there is a wide range of counterexamples to your assertion that YouTube Music is this siloed thing that's only music direct from publishers.
Here's a more straightforward example. I search for "action bronson blue chips 2" [1]
The top result is "Action Bronson Blue Chips 2 ((Full Album)) - Please Subscribe" from user 'Lpmixtapes compilation and mixtapes...'[2]
The official release [3] is a page scroll down.
So, I don't think it's reasonable to call people "terrible at search" when these things literally come up as top results in search and are fair game for the recommendation algo to slide into your stream, or "full of shit" when they can give you specific examples of how things you've said are wrong.
Why are you so sure that your experience is the one true YouTube Music experience, and several other people telling you they have other experiences are "making shit up"?
