I'm a little confused at how people are getting these bad recommendations from YouTube, because my recommendations - at least on my Samsung TV's YouTube app - are mostly spot on. It knows I'm interested in music production, long form studio tours and interviews, 8-bit retro gear & repair, and that's pretty much all it recommends. It can infer that from my subscriptions, but seems to go more by what I actually watch & like.

I assume you are clicking like on the videos that you enjoyed? Do you treat YouTube like a spam filter and rate things as "Not Interested" if it recommends something wrong? Or maybe Google's algorithms are just really really terrible outside of US / UK / Canada / Aus?

On the other hand, my recommendations on the mobile app aren't as good. It's almost as if YouTube treats each client as a separate account/context, even though I'm signed in on all of them.
