That's exactly my point.

As the Contribute question stands, I might put Symphony X and Johnny Cash on my list of favorites, which would make the site more likely to recommend one in response to the other. But in real life, if someone asked me what I'd recommend to a Johnny Cash fan, there's no way I'd answer Symphony X.

And I propose that the way to address this is to not ask the user "what are your [unrelated] favorites", but rather, "pick a recent moment, and tell us what music you would have most enjoyed hearing at that time". That implies a stronger link than simply that the listed artists share a spot on my list of unrelated favorites.

Reading comprehension fail on my part!
