YouTube has done good by me as well; I've found all sorts of music thereby that I otherwise would never have found. Perhaps the YouTube algorithm is indeed run as you describe - showcasing music which is just a few levels more obscure / unknown than what you already have heard?
It's quite possible that the YouTube model does what I describe. Unfortunately it's hard to really know, though, for two reasons: (1) the code/model isn't public, (2) even if it were public, these models are fundamentally somewhat opaque and hard to "understand".
