It was closed as being opinion-based, before being reopened. I had initially worded the title poorly, but was surprised at the quick close as I thought the question content showed that there was a clear statistical distinction which may have some clear reasons that someone could explain.
Are the lyrics of Yoko Kanno's "Moon" gibberish or intelligible? is another question that may have initially been poorly-titled, but a read of the question itself should have revealed a reasonable question.
https://musicfans.stackexchange.com/questions/342/how-did-pumped-up-kicks-become-such-a-big-success seems another example where there may be a non-opinion based answer possible, as (in my opinion) there is in reasons behind K - pop success.
Are we perhaps a little sharp on the button to close things as opinion-based?
