we well see ..maybe if it was only planned as a single release then scrapped...
well then
Edit: very recently..
when was that

that he promote it there playing it on that TV show instead of his two current singles...shows tthe possibilty of black cloud being a single
(also did play it a bit earlier on jimmy kimmel
