He's obviously talking about the ones that aren't, such as the 'Discover Weekly' and the way it will guess at what to play next after an album finishes.

That said, I do think their recommendation engine produces decent results, but I don't think the composition of the list is something it focuses on. Rather its just a list of unrelated tracks it thinks you'd be inclined to enjoy on their own.
